+//INPUT

+//The water gas shift reaction is given by : CO2(g)+H2(g)--->CO(g)+H2O(g)

+T=298.15;//temperature in K

+del_Gf=[-137.327;-228.600;-394.815;0];//the standard Gibbs free energy of formation of CO(g),H2O(g),CO2(g) and H2(g) in kJ

+n=[1;1;-1;-1];//stoichiometric coefficients of CO(g),H2O(g),CO2(g) and H2(g) respectively (no unit)

+R=8.314;//universal gas constant in J/molK

+

+//CALCULATION

+//calculation of the standard Gibbs free energy of reaction at 298.15K using Eq.(14.1) in kJ

+del_G=(n(1,:)*del_Gf(1,:))+(n(2,:)*del_Gf(2,:))+(n(3,:)*del_Gf(3,:))+(n(4,:)*del_Gf(4,:));

+Ka=exp((-(del_G*10^3))/(R*T));//calculation of the equilibrium constant using Eq.(14.9) (no unit)

+

+//OUTPUT

+mprintf('The standard Gibbs free energy of the water gas shift reaction at 298.15K=%0.3f kJ \n',del_G);

+mprintf('The equilibrium constant of the water gas shift reaction at 298.15K=%0.3e \n',Ka);
