NEET Chemistry Chemical Kinetics Questions Solved


For the non-stoichiometric reaction 2A + B  C +D, the following kinetic data were obtained in three separate experiments, all at 298 K.



The rate law for the formation of C is:

(a) d[C]/dt = k[ A][B]

(b) d[C]/dt = k[ A]2[B]

(c) d[C]/dt = k[ A][B]2

(d) d[C]/dt = k[ A]

(d) Let rate expression be r = k[ A]m[B]n

     1.2 x 10-3 = k(0.1)m(0.1)n             ......(i)

     1.2 x 10-3 = k(0.1)m(0.2)n             ......(ii)

     2.4 x 10-3 = k(0.2)m(0.1)n             ......(iii)

     By (i) and (ii) n=0

     By (i) and (iii) m=1

     dc/dt = K[A]1
