For a chemical reaction A → B , it was found that concentration of B is increased by 0 . 2 mol L - 1 in 30 min. The average rate of the reaction is ________ × 10 - 1 mol L - 1 h - 1 . (in nearest integer)

Correct answer

0

Step-by-step solution

A ⟶ B t = 0           0 t = 30   min    0 . 2 M Av. rate of reaction = - Δ [ A ] Δ t = Δ [ B ] Δ t = ( 0 . 2 - 0 ) 1 2 = 0 . 4 = 4 × 10 - 1   mol / L × hr
