JEE Main Chemistry question

Not in JEE Main or NEET syllabus

One of the reasons for the greater reactivity of finely divided platinum catalyst is that it has:

(A)Particles which are small in dimensions, almost atomic
(B)Particle size which can spread easily through the whole of the reactants
(C)Much larger surface areaCorrect
(D)A physical state only in which it can react quickly

Answer: (C)

Solution

Finely dividing platinum dramatically increases the total surface area exposed per unit mass, providing many more active centres on which reactant molecules can be
