Compressibility Calculator

Compressibility and Ideal Gas Approximations

This form submits information to an interactive model which calculates compressibility and pressure based on several factors. Graphs will be generated for several different temperatures, each graph showing the pressure and compressibility over a range of volumes. Input the temperatures separated by a space or comma at which you want to calculate these graphs. Up to 10 temperatures may be entered. These temperatures are proportions of the critical temperature, which is a factor in the compressibility. The critical temperature depends on the gas, but is usually low. At critical temperature, pressure, and volume, the gas changes phase.

Compressibility expresses how much a gas is behaving like an ideal gas under any conditions. If the compressibility equals one, then the gas is behaving exactly like an ideal gas. If the compressibility deviates much from one, then the ideal gas equation will not accurately model the real gas under those conditions. This script uses the Beattie-Bridgeman equation to calculate the behavior of the gas, even when not acting ideally.

Enthalpy and Gibbs Free Energy Calculator

Introduction : the purpose of this calculator is to calculate the value of the enthalphy of a reaction (delta H) or the Gibbs free energy of a reaction (delta G). The form below provides you with blanks to enter the individual enthalpies or free energy d ata points for a given reaction. Once entered, simply click on the "Evaluate" button to compute the appropriate value.

Note: if you do not have a second or third reactant or product, simply enter the value of "0" in the form.

The form below calculates the reaction enthalphy for:

NO₃ + H₂O -----> HNO₃ + OH

Keep in mind the following rules:

Enthalphy Change	Spontaneous Reaction?
Exothermic (dH <>	Yes, dG <>
Exothermic (dH <>	If \|T dS\| < \|dH\|
Endothermic (dH > 0)	If T dS > dH
Endothermic (dH > 0)	No, dG > 0

Arrhenius Evaluation

The Arrhenius Equation

Background reading:

Common sense and chemical intuition suggest that the higher the temperature, the faster a given chemical reaction will proceed. Quantitatively this relationship between the rate a reaction proceeds and its temperature is determined by the Arrhenius Equation. At higher temperatures, the probability that two molecules will collide is higher. This higher collision rate results in a higher kinetic energy, which has an effect on the activation energy of the reaction. The activation energy is the amount of energy required to ensure that a reaction happens.

This calculator calculates the effect of temperature on reaction rates using the Arrhenius equation.

k=A*exp^(-E_a/R*T) where k is the rate coefficient, A is a constant, E_a is the activation energy, R is the universal gas constant, and T is the temperature (in degrees Kelvin).

R has the value of 8.314 x 10^-3 kJ mol^-1K^-1

You should use this calculator to investigate the influence of temperature on the rate coefficient.

This calculator allows you to perform three different calculations:

This Excel AddIn contains a moderate databank of chemicals and a nice array of physical properties. It also contains Excel functions that can be pasted into worksheets (be sure you have one open first). You'll find the AddIn under the Tools menu.

Units Conversions

These handy little programs are just about everywhere. There a good and bad side to this one. The bad side is that is runs in DOS, the good side is that it shows many different conversions at once.

The Reactor Lab

A fantastic program designed to help students gain a better understanding of reactor simulations...and best of all....it's free!

Insulation Calculation Programs

Two programs included to help you with insulation calculations. The "Economic Thickness Calculator" will recommend the appropriate insulation thickness based on energy savings. The "Insulated Pipe Temperature Prediction Spreadsheet" will help you predict the temperature inside a pipe and linear heat loss.

Vapor Pressure of Binary Liquid Mixtures

Use this spreadsheet to find the vapor pressure of binary liquid mixtures. Based on fugacity corrected values from Antoines Law, this spreadsheet give accurate results with minimal inputs.

Physical Property Data Spreadsheet

This spreadsheet for Excel 97 contains data such as boiling and freezing points, critical data, density, vapor and liquid heat capacities, liquid viscosity, vapor pressures, and more for 468 chemicals.

Cooling Tower Calculator

This handy little DOS program will calculate the tower characteristic or cold water temperature for a given cooling tower with just a few inputs. (See Cooling Tower article here at the "Resource Page")

Pipe Size Optimization for Carbon and Stainless Steel Pipes

This simple spreadsheet will calculate the most economical pipe diameter for a system based on flowrate, fluid density, and fluid viscosity. The sheet is to be used for turbulent flow in carbon or stainless steel pipes. It is designed to run on Excel 97 or higher and utilizes the Solver function so it must be installed as well.

Validating Binary VLE Data

Check the thermodynamic consistency of your binary VLE data with this easy to follow analysis. Complete with spreadsheet to save you time!

Costing Distillation Columns

Enter some basic data and this EXCEL ADD-IN will do the rest. Check out the specifications of the program.

Vapor-Liquid Equilibrium Calculator

This program uses data stored in its own Excel Spreadsheet to formulate VLE and other thermodynamic data by several popular correlations. Database of components is expandable so you can add your own components. Developed by William D. Kovats.
