The temperature coefficient of most of the reactions lies between

Assertion: Temperature coefficients of most of the reactions lies between 2 and 3 . Reason: Increases in temperature increases the number of collisions.

Two first order reactions proceed at 25^(@)C at the same rate. The temperature coefficient of the rate of the first reaction is 2 and that of second reaction is 3 . Find the ratio of the rates of these reactions at 75^(@)C .
