NEET Chemistry Chemical Kinetics Questions Solved


The rate constant of a first order reaction is 10-3 min-1 at 27°C. The temperature coefficient of this  reaction is 2. The rate constant at 17°C will be :

(1) 10-3 min-1

(2) 5  x 10-4 min-1

(3) 2 x 10-3 min-1

(4) 10-2 min-1

(2) KT1/KT2 =μT/10= 10-3/KT1=μ10/10 = 2

      KT1 = 10-3/2 = 0.5 x 10-3 =5x 10-4 min-1
