Question
the reaction 2A + B ---> C + 2D was found to be first order in A and B. Which of the following is true?a. rate=k[A]^2[B] b. rate=k[A]^2 c. rate of consumption of A = rate of consumption of B d. 2 x (rate of formation of C) = rate of formation of D e. the reaction is first order overall the reaction 2A + B ---> C + 2D was found to be first order in A and B. Which of the following is true?
a. rate=k[A]^2[B] b. rate=k[A]^2 c. rate of consumption of A = rate of consumption of B d. 2 x (rate of formation of C) = rate of formation of D e. the reaction is first order overall the reaction 2A + B ---> C + 2D was found to be first order in A and B. Which of the following is true?

Explanation / Answer
answer : d. 2 x (rate of formation of C) = rate of formation of D
2A + B ------------> C + 2D
rate = k [A][B]
rate = 1/2 d[A] / dt = d[B] / dt = d[C]/dt = 1/2 d[D]/dt
rate of consumption of A = 2 x rate of consumption [B]
2 x (rate formation of [C] ) = rate formation of [D]
