For the given reaction, A + B ⟶ Products Following data are given: initial conc. (m/L) initial conc. (m/L) initial conc. m L - 1 s - 1 A 0 B 0 0.1 0.1 0.05 0.2 0.1 0.1 0.1 0.2 0.05 Calculate the rate constant.

Step-by-step solution

Assume rate law expression Rate = k A x B y 0. 0 5 = k 0. 1 x 0. 1 y ⟶ I 0. 1 0 = k 0. 2 x 0. 1 y ⟶ II 0. 0 5 = k 0. 1 x 0. 2 y ⟶ III II I ⇒ 2 = 2 x ∴ x = 1 I II I ⇒ 1 = 2 y = 2 0 ∴ y = 0 Order w.r.t. A is one Order w.r.t. B is Zero Rate law expression is Rate = k A 0. 0 5 = k 0. 1 1 k = 0.0 5 0 · 1 = 0 · 5 sec - 1
