QUESTION:

For the reaction \(X_{2}\) + Y + Z → XY + XZ it is found that doubling the concentration of \(X_{2}\) doubles the reaction rate, tripling the concentration of Y triples the rate, and doubling the concentration of Z has no effect. (a) What is the rate law for this reaction? (b) Why is it that the change in the concentration of Z has no effect on the rate? (c) Suggest a mechanism for the reaction that is consistent with the rate law.
