The rate of reaction is doubled for every 10ºC rise in temperature. The increase in rate as result of increase in temperature from 10ºC to 100ºC is

A.112

B.512✓ Correct

C.400

D.256

Explanation

Temperature coefficient = 2 as rate of reaction doubled for energy 10 C rise in temperature. Now, rate of reaction increases by n . Since, here is 2 & 2 1 10 T T n We have, rate of reaction increased by 100 10 9 10 2 2 times i.e., 512 times CHEMICAL KINETICS 23
