Question

consider the following data for the reaction A+B = product
determine the order of the reaction with respect to A and with respect to B and the overall order of the reaction​

Answer 1

Answer:

Rate = k[A]p[B]q

Comparing experiments 2 and 3,

(Rate)2=k[0.2]p[2.0]qK[0.2]p[1.0]q=8.4×10−38.4×10−3=1

[2]q=[2]0,q=0

Comparing experiments 1 and 2,

(Rate)2=k[0.20]p[1.0]q=8.4×10−3

(Rate)1=k[0.10]p[1.0]q=2.1×10−3

Dividing eqn. (iii) by (iv),

(Rate)2Rate1=k[0.20]p[1.0]qk[0.10]p[1.0]q=8.4×10−32.1×10−3=4

Order w.r. to A = 2, B=0, Overall order = 2.
