Chemistry Chemical Kinetics MHT CET

A chemical reaction was carried out at 300 K and 280 K. The rate constants were found to be and respectively. Then

(A)
(B)Correct
(C)
(D)

Answer: (B)

Solution

Taking the usual temperature coefficient of 2 (rate doubles for every 10 K rise), the 20 K fall from 300 K to 280 K reduces the rate constant to
