Correct Option (d) 1.125 x 102L2 mol-1sec-1
From data (1) and (2) we observe that
On doubling the concentration of A, rate become four times
:. order w.r.t A = 2
From data (2) and (3) we observe that
On making the concentration of B to one half, rate also become one half.
:. order w.r.t B = 1
overall order = 3
As only (d) option have unit of rate constant corresponds to third order.
