Question

In most case, for a rise of 10K temperature the rate constant is doubled to tripled. This is due to the reason that

Options

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.non of these

Solution

For a 10 K rise in temperature, collision frequency increases meraly by 1 to 2% but thenumber of effective collisions increases by 100 to 200%.
