In a reaction between two substances A and B, the rate is found to be proportional to the concentration of A at all concentrations studied. At low concentrations of B, the rate of the reaction is found to be proportional to [B], but to level off at high concentrations of B. What is a reasonable explanation for the observed dependence of rate on [B]
