Alters the reaction mechanism

Vedclass · Answer

(C) catalyst provides an alternative pathway for the reaction with lower activation energy. By lowering the activation energy,a larger fraction of molecules can cross the energy barrier,which effectively increases the rate of the reaction. While the frequency of collisions is determined by temperature and concentration,the catalyst's primary role is to alter the reaction mechanism to a lower energy path. However,in the context of standard multiple-choice questions regarding the effect of catalysts on reaction rates,option $C$ is the most scientifically accurate description of how a catalyst functions.
