Select the correct statement(s)

The rate law of elementary reaction 2 A → B + C

(i) According to law of mass action rate = K[A]² Order = 2

(ii) The rate law for the complex reaction

A + B → Cmight not be rate = K[A][B]

Complex reaction are depends on mechanisms

Based on mechanism find out the slow step if the partial orders differ from the co-efficient in the balanced reaction the reaction must be complex.
