Question

In homogeneous catalysis_________

(a) All reactants are in the same rate

(b) The catalyst is in a different state to the reactants

(c) The reactants and catalyst are in the same rate

(d) All the products are in the same state

I got this question in examination.

Question is from Concentration Gradients and Reaction Rates in Solid Catalysts in division Heterogenous Reactions of Bioprocess Engineering

Answer 1

The correct choice is (c) The reactants and catalyst are in the same rate

The explanation is: Homogeneous catalysis refers to catalytic reactions where the catalyst is in the same phase as the reactants. Homogeneous catalysis applies to reactions in the gas phase and even in solids.
