The reaction 2A + B $\rarr$ products is second order with respect to A and zero-order with respect toB. Starting with 0.135 M of A, what is the concentration of A after 35 min if the rate constant is 0.11 M^-1s^-1

Question

Quizplus · Accepted Answer

For a second-order reaction, the integrated rate law is 1/[A] = kt + 1/[A]₀. Plugging in the values: 1/[A] = (0.11 M⁻¹s⁻¹)(2100 s) + 1/0.135 M, solving gives [A] ≈ 4.2 x 10⁻³ M.
