Statement-I: Lead chamber process is an example of homogeneous catalysis.Statement-II: MnO2 is the auto-catalyst in the reaction of KMnO4 vs H2C2O4in acidic medium.

Statement-I: 2SO2(g)+O2(g)→NO(g)2SO3(g) is lead chamber process. Reactants and catalyst are in same phase.Statement-II: Initially the reaction between KMnO4 and H2C2O4 in acidic medium is slow. But slowly rate of reaction starts increasing because the product Mn+2 formed catalyzes the reaction.
