In most cases, for a rise of \( 10 \mathrm{~K} \) temperature the rate constant is doubled to tribled. This is due to the reason that
(a) collision frequency increases by a factor of 2 to 3 .
(b) fraction of molecules possessing threshold energy increases by a factor of 2 to 3
(c) Activation energy is lowered by a factor of 2 to 3 .
(d) none of these
