Vedclass · Answer

(A) catalyst works by providing an alternative reaction pathway with lower activation energy. The reaction occurs on the surface of the catalyst. By converting the catalyst into a finely divided form,the total surface area available for the reactant molecules to adsorb increases significantly. This leads to a higher rate of reaction,making the catalyst more effective.

Assertion: $A$ catalyst is more effective in finely divided form.
Reason: Finely divided form has more surface area.
