Question

For a reaction 2A + B + 3C -> D + 3E, the following data is obtained: Exp. 1: [A]=0.01, [B]=0.01, [C]=0.01, Rate=2.5x10^-4; Exp. 2: [A]=0.02, [B]=0.01, [C]=0.01, Rate=1.0x10^-3; Exp. 3: [A]=0.01, [B]=0.02, [C]=0.01, Rate=2.5x10^-4; Exp. 4: [A]=0.01, [B]=0.02, [C]=0.02, Rate=5.0x10^-4

Prashant Kotian · Accepted Answer

Correct answer: B. Comparing Exp 1 & 2: [A] doubles, rate increases 4 times => order w.r.t. A = 2. Comparing Exp 1 & 3: [B] doubles, rate is constant => order w.r.t. B = 0. Comparing Exp 3 & 4: [C] doubles, rate doubles => order w.r.t. C = 1. Thus, order is 2, 0, 1.
