In homogeneous catalytic reactions, the rate of reactiona)depends upon...
Homogeneous catalytic reactions are those in which the catalyst is in the same phase as the reactants. In such reactions, the rate of reaction depends upon the concentration of the catalyst, which is explained in the following points:
Role of Catalyst in Homogeneous Reactions
- Catalysts are used to increase the rate of reaction by providing an alternative pathway with lower activation energy.
- The catalyst participates in the reaction by forming an intermediate complex with reactants, which subsequently leads to the formation of products.
- The catalyst is regenerated at the end of the reaction, and hence, its concentration remains constant throughout the reaction.
Effect of Catalyst Concentration on Rate of Reaction
- As the concentration of the catalyst increases, the number of active sites available for the reaction also increases.
- This results in a higher rate of reaction as more reactants are able to form the intermediate complex with the catalyst.
- However, beyond a certain concentration, the rate of reaction reaches a maximum as all the active sites are occupied, and further increase in catalyst concentration does not affect the rate of reaction.
Dependence of Rate of Reaction on Catalyst Concentration
- The rate of reaction in homogeneous catalytic reactions is directly proportional to the concentration of the catalyst.
- This is because the catalyst plays an active role in facilitating the reaction by lowering the activation energy, and hence, its concentration affects the number of active sites available for the reaction.
- However, the concentration of the reactants also affects the rate of reaction, and hence, the rate law for such reactions involves both the reactant and catalyst concentrations.
Therefore, the correct answer to the given question is option 'B', i.e., the rate of reaction in homogeneous catalytic reactions depends upon the concentration of the catalyst.

In homogeneous catalytic reactions, the rate of reactiona)depends upon...
The rate of reaction depends on the surface area of the catalyst. These reactions are generally slow. In homogeneous catalysis, rate majorly depends on surface area
