Statement 1 : KP=KC for all reversible reaction.Statement 2 : At constant temperature, the pressure of the gas is proportional to its concentration.

Statement 1 is false but statement 2 is true.KP≠KC for all reactionKP=KCRT∆n∆n=number of moles of products - number of moles of reactants in the balanced chemical equation.So, if for a reaction ∆n=0. Then KP=KC
