Step-by-step solution

Comparing expt. (1) and expt. (2). When [B] is doubled rate of reaction doubles. Reaction is first order is B . Comparing expt. (2) and expt (3). When [C] is doubled rate of reaction doubles. Reaction is first order in C . Comparing expt. [3] and expt [4]. When [A] is doubled rate of reaction remains unchanged. Reaction is zero order in A . Rate law =K[A]^0[B]^ [C]^ Using data of expt. (1) we get aligned & 2.4 10⁻⁶=K[0.02]^0[0.1]^1[0.03]^1 & 2.4 10⁻⁶=K 1 0.1 0.03 & K= 2.4 10⁻⁶ 3 10⁻³ =0.8 10⁻³=8.0 10⁻⁴ ~L ~mol ⁻¹ ~
