Stoichiometry Gas Phase

About this app

Gas Phase Stoichiometry is an ultimate tool for parameterisation of unidirectional chemical reactions that occur in a gas phase. The application balances chemical reactions, derives molar masses, moles, pressures and volumes of reactants and products based on their chemical formulas, stoichiometric coefficients and user defined temperature, enclosing volume or external pressure.  Application provides two layouts: the first is for reactions occurring at the user defined constant volume, where moles and partial pressures of compounds are calculated and the second is for reactions occurring at the user defined constant external pressure, where moles and volumes of gaseous compounds are analysed.   User is required to provide initial or final (after reaction accomplishment) pressures (volumes) or moles of any of the reaction component, to calculate all required and obtained pressures (volumes) and moles for all components. If data is available for several components, then limiting reagent will be found based on reaction stoichiometry.  Either mole or pressure (volume) should be filled in for each compound, but if both are provided and they do not match, then moles value will have a preference and the stoichiometrically matching pressure (volume) will be recalculated.   The app can get data directly from Stoichiometry application for calculations of pressures/volumes of gaseous compounds. The data may include balanced chemical reaction, molar weights and initial mole quantities.   For further details and theoretical background please visit www.volard.wordpress.com
