Reaction Thermodynamics helps in evaluation of main thermodynamic parameters of a chemical reaction.  Application calculates the following parameters: - Standard free Gibbs energy, enthalpy and entropy from formation energy parameters. - Reaction quotient (Q) from concentrations, pressures and reaction stoichiometry. - Non standard energy parameters (dG, dH, dS) from standard ones, quotient and temperature. - Reaction equilibrium constant, Keq. - Van't Hoff relation to follow change in equilibrium constant with temperature assum...

Thermochemistry helps in evaluation of enthalpy or heat release/absorption of a system undergoing numerous temperature changes and phase transitions. The calculations take advantage of known values of heat capacity at constant pressure (Cp) and molar or per gram enthalpy of phase transition. Amount of compound can be defined in grams or moles, in a way that Cp and enthalpy units would match. App provides enthalpy values for each step. Negative enthalpy points to exothermic process – heat release, while positive one to endothermic -...

The “Chemical Kinetics” is an ultimate tool for solving all kind of chemical kinetics problems. It deals with time dependent quantitative analysis of chemical reactions. Specifically, this application solves chemical reaction rate equations and provides graphical representation of reagent and product concentrations vs time. Additionally, app calculates half-life times and equilibrium constants, where it is appropriate. Theoretical Background: For a general chemical reaction: aA + bB => cC + dD...
