Which of the following graphs best represents of penicillin, if the reaction is second order with respect to penicillin? For the reaction X_2 + Y + Z rightarrow XY + XZ, it is found that doubling the concentration of X_2 doubled the reaction rate, tripling the concentration of Y triples the rate, and doubling the concentration of Z has no effect. What is the rate law for this reaction? What is the unit for the rate constant for this reaction?...
