The catalysis in which the catalyst and the reactants are In the same phase is known?
Correct answer: B. Homogeneous catalyst
- A. Heterogeneous catalyst
- B. Homogeneous catalyst
- C. Slow
- D. Fast
Explanation
In homogeneous catalysis, the catalyst and the reactants are in the same phase, typically a liquid or gas. The catalyst molecules can directly interact with the reactant molecules, facilitating the reaction without forming a distinct phase or boundary between them.

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.
