Calculate the rate of reaction from the ...

Calculate the rate of reaction from the following rate law:
`-(d[A])/(dt) = k[A]^(1)[B]^(2)`
when the concentrations of A and B are 0.01 M and 0.02 M respectively and `k=5.1xx10^(-3)L^(2)"mol"^(-2)s^(-1)`.

Text Solution

Verified by Experts

`-(d[A])/(dt)=k[A]^(1)[B]^(2)`
Substituting the values of k, [A] and [B], we have
Rate of reaction `=5.1xx10^(-3) xx (0.01)(0.02)^(2)=5.1xx10^(-3)xx10^(-2)xx4xx10^(-4)`
`=20.4 xx 10^(-9) =2.04xx10^(-8)"mol L"^(-1)s^(-1)`
