Question

For a reaction x +y + z → products, the rate law is given by rate = k [x]^3/2 [y]^1/2 what is the overall order of the reaction and what is the order of the reaction with respect to z.

Answer 1

Rate = k [x]^3/2[y]^1/2

overall order = \(\Big(\frac{3}{2}+\frac{1}{2}\Big)\) = 2

i.e., second order reaction. Since the rate expression does not contain the concentration of Z , the reaction is zero order with respect to Z.
