Initial rate data for is collected: Exp 1: . Exp 2: . Exp 3: . What is the rate law?

Question

Initial rate data for $A + B ightarrow C$ is collected: Exp 1: $[A]=0.1, [B]=0.1, R=1.2	imes10^{-3}$. Exp 2: $[A]=0.1, [B]=0.2, R=1.2	imes10^{-3}$. Exp 3: $[A]=0.2, [B]=0.1, R=2.4	imes10^{-3}$. What is the rate law?

Prashant Kotian · Accepted Answer

Correct answer: C. Comparing Exp 1 & 2: doubling [B] while keeping [A] constant does not change the rate. Order w.r.t B is 0. Comparing Exp 1 & 3: doubling [A] while keeping [B] constant doubles the rate. Order w.r.t A is 1. The rate law is .
