A reaction in which catalyst is used is called catalysis. Which of the following is an example of heterogeneous catalysis?
Correct answer: A. A
- A. A
- B. B
- C. C
- D. D
Explanation
Heterogenous catalysis: The catalysis in which reactants and catalyst are in different phase.Homogenous catalysis: The catalysis in which reactants and catalyst are in same phase.In option A, SO2 and O2 are gases while V2O5 is solid. So, it is heterogenous catalysis.While in other two reactions, the catalyst and reactants are in same phase, so they are example of homogenous catalysis.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
