Hint: Catalyst is a common word that you might come across while studying chemistry especially while learning about chemical reactions. While some of the chemical reactions occur quickly, some take a long time and require extra materials or effort. So, catalysts are defined as those substances which alter the rate of reaction by changing the path of reaction.
Complete answer:
A catalyst can be either solid, liquid or gaseous catalyst. A catalyst increases reaction rates in a slightly different way from other methods of increasing reaction rate. The function of a catalyst is to lower the activation energy so that a greater proportion of the particles have enough energy to react.
Types of Catalysts are:
1) Positive Catalysts : Catalysts which increase the rate of a chemical reaction are positive catalysts.
2) Negative Catalysts: Catalysts which decrease the rate of reaction and negative catalyst.
The function of a catalyst is to lower the activation energy so that a greater proportion of the particles have enough energy to react.
A catalyst increases the rate of reaction by decreasing the activation energy of the reaction. It does not affect the Gibbs free energy \[\Delta G\] of the reaction.
Thus, the statement given in option (B) is incorrect.
Note: In essence, catalysts encourage molecules to react and make the whole reaction process easier and efficient.
