The initial velocity of a hypothetical reaction A + B → C was measured for various initial concentrations of A and B, and the experimental results were as follows: Indicate the alternative that shows the reaction rate law and the value of the rate constant:
a) v = k[A]^2; k = 2.0 x 10^-2 L^2.mol^-2.s^-1 b) v = k[B]^2; k = 2.0 x 10^-2 L^2.mol^-2.s^-1 c) v = k[B]^2; k = 4.0 x 10^-2 L^2.mol^-2.s^-1 d) v = k[A][B]; k = 4.0 x 10^-2 L^2.mol^-2.s^-1 e) v = k[A]^2[B]; k = 4.0 x 10^-2 L^2.mol^-2.s^-1
A alternativa correta é a letra d) v = k[A][B]; k = 4.0 x 10^-2 L^2.mol^-2.s^-1. Essa é a única opção que representa a lei da velocidade da reação corretamente, levando em consideração as concentrações iniciais de A e B.
