Answer to Question #163102 in Physical Chemistry for khan

Question

The following kinetic data (𝑣0 is the initial rate) were obtained for the reaction: 2𝐼𝐶𝑙(𝑔) + 𝐻2(𝑔) → 𝐼2(𝑔) + 2𝐻𝐶𝑙(𝑔) Experiment [𝐼𝐶𝑙]0 (𝑚𝑚𝑜𝑙. 𝑑𝑚−3 ) [𝐻2]0 (𝑚𝑚𝑜𝑙. 𝑑𝑚−3 ) 𝑣0 (𝑚𝑚𝑜𝑙. 𝑑𝑚−3 ) 1 1.5 1.5 3.7 x 10-7 2 3.0 1.5 7.4 x 10-7 3 3.0 4.5 22 x 10-7 4 4.7 2.7 ? (a) Write the rate law for the reaction [2] (b) From the data, determine the value of the rate constant [2]

Answer 1

Rate law is expression where we defined rate of reaction with a tive mass of reactant with some power .( order )

Order is experimental may be zero , fraction positive and negative .
