Question

In most cases, for a rise of 10 K temperature, the rate constant is doubled to tripled. 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

Tardigrade Admin · Accepted Answer

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

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

collision frequency increases by a factor of 2 to 3 .

fraction of molecules possessing threshold energy increases by a factor of 2 to 3

activation energy is lowered by a factor of 2 to 3 .

none of these

For a $10 K$ rise in temperature, collision frequency increases merely by $1$ to $2%$ but the number of effective collisions increases by $100$ to $200%$ .
