The experimental data for the reaction 2...

The experimental data for the reaction `2A+B_(2)to2AB` is given below. Based on the data write the rate equation.
`{:("[A],mol L"^(-1),[B_(2)]", mol L"^(-1),"Rate, mol L"^(-1)s^(-1)),(0.5,0.5,1.6xx10^(-4)),(0.5,1.0,3.2xx10^(-4)),(1.0,1.0,3.2xx10^(-4)):}`

Text Solution

Verified by Experts

Keeping [A] constant, doubling `[B_(2)]` the rate is doubled. Hence, order with respect to `B_(2)` is `1`. Keeping `[B_(2)]` constant, doubling [A] there is no change in the rate. Hence, order with respect to A is zero. The rate equation is rate `=K[A)^(@)[B_(2)]^(1)(or)"rate"=K[B_(2)]`.
