For a reaction `x+y to z ` data is as follows :

which one is the rate law equation ?

Options

A. Rate `=k[x][y]`
B. rate`=k[x^(0)][y]`
C. Rate `=k[x][y]^(2)`
D. Rate `=k[x][y]^(0)`

Answer

D

Explanation

Compare experiment no .1 and 2 .
[y] is constant and [x] is doubled , the rate becomes 2 times I .e, `2^(1)`
` therefore ` for x,` n=1`
Compare experiment no 3 and 4.
[x] is constant and [y] is 3/2 , the rate is same , hence the rate is independent of [Y] , n =0
` therefore ` Rate law is , Rate `=k [X][Y]^(0) `
