Dear Student,

The overall order for the reaction can be identified by first finding out the individual orders of reaction for A and B.
Let a and b be the orders of reaction w.r.t A and B.

Thus, rate of reaction = r = kAoaBob
Making use of the first and second data,0.23 × 10-2 = k0.01a0.03b0.92 × 10-2 = k0.04a0.03bDividing the two equations,0.23 × 10-20.92 × 10-2=k0.01a0.03b k0.04a0.03b14=14aTherefore, a = 1Now, making use of second and third data,0.92 × 10-2 = k0.04a0.03b3.68 × 10-2 = k0.04a0.06bDividing the two equations,0.92 × 10-23.68 × 10-2=k0.04a0.03b k0.04a0.06b14=12bTherefore, b = 2Overall order = a+b = 1 + 2= 3
