Answer to Question #38266 in Physical Chemistry for Abhishek singh
if in a chemical reaction No. of molecules not change;volumes of gases are given in place of molar concentrations.Can we put these volumes in the equation(in place of molar concentrations)to find the equilibrium const.of the reaction?if yes,than why?
When the number of moles in both part of the equation is equal, then the equilibrium constant is dimensionless, and there is no matter which value proportional to the amount of substance is used. However when the total moles in both parts are not the same, you should follow the dimensionality of the equilibrium constant.
