Explanation / Answer

A + 2B -----> C + D

Rate of reaction = k*[A]n*[B]m ; where k = rate constant, n & m are the order of the reaction w.r.t A & B respectively

Thus,

0.0165 = k*0.28n*0.2m ......(1)

0.0165 = k*0.28n*0.4m ......(2)

0.066 = k*0.56n*0.2m .......(3)

Now, (2) /(1) gives

1 = 2m

or, m = 0......(4)

Now, (3)/(1) gives

4 = 2n

or, n = 2......(5)

Using the values of 4 & 5 in 1 we get

0.0165 = k*0.282

or, rate constant , k = 0.21 M-1s-1
