The reaction A + B → products is first order in A, first order in B, and second order overall. Consider that the starting concentrations of the reactants are [A]₀ and [B]₀, and that x represents the decrease in these concentrations at the time t. That is, [A]_t = [A]₀ - x and [B]_t = [B]₀ - x. Show that the integrated rate law for this reaction can be expressed as shown below.
