NEET Chemistry Chemical Kinetics Questions Solved


The rate constant (K) for the reaction 2A +B  Product was found to be 2.5x10-5 litre mol-1 sec-1 after 15 sec, 2.60 x10-5 litre mol-1sec-1 after 30 sec and 2.55 x10-5litre mol-1 sec-1 after 50 sec. The order of reaction is:

(a) 2

(b) 3

(c) zero

(d) 1

(a) K does not change with time; also unit of K suggest it to be II order 

     Now, r = k[A] = 10-2x0.1 = 102Msec-1
