For the non-stoichiometry reaction, 2A + B → C + D, the following kinetic data were obtained in three separate experiments, all at 298 K. Initial Concentration (A) | Initial Concentration (B) | Initial rate of formation of C (mol L^-1 S^-1) 0.1 M | 0.1 M | 1.2 × 10^-3 0.1 M | 0.2 M | 1.2 × 10^-3 0.2 M | 0.1 M | 2.4 × 10^-3 The rate law for the formation of C is
- dc/dt = k[A][B]
- dc/dt = k[A]^2[B]
- dc/dt = k[A][B]^2
- dc/dt = k[A]
Correct answer: dc/dt = k[A]
Solution
The correct option indicates that the rate of formation of C depends only on the concentration of A, as the rate remains constant despite changes in the concentration of B, suggesting that B does not influence the reaction rate.
