Calculate the order of the reaction `A to ` product from the following data :
.

Explanation

Let the order be n .
Applying rate law for the first and second set of readings ,
we have
rate = `0 xx10^(-5) = k (0.0025) ^(n)" "…(1)`
and , rate = `5xx10^(-5) = k (0.005)^(5)" "…(2)`
Dividing (1) by (2) , we get ` 2= (1/2)^(th)`
` or n = - 1 `
Thus the order of the reaction is = - 1
