Question

The rate of reaction increases rapidly on slightly increase in temperature, because
(a) The number of activated reactants increases.
(b) The number of collisions increases.
(c) The number of free path increases.
(d) Heat of reaction increases.

Answer 1

Answer:

Here on increasing temperature tge energy of reactants increase which means the option 1 that the number of particals having required energy increases.

But the more significant increase is seen in the number of collisiobs due to increase in energy. Thus factor greatly influence the rate more tgan the 1 option.

Thus the final correct answer is( 2)
