For the reaction X₂ + Y + Z $\rarr$ XY + XZ, it is found that the rate equation is rate = k [X₂][Y]. Why does the concentration of Z have no effect on the rate

Question

Quizplus · Accepted Answer

If the rate equation does not include the concentration of a reactant, it means that the reaction rate is not affected by the changes in the concentration of that reactant. In this case, the concentration of Z does not affect the rate, which indicates that Z is not involved in the rate determining step. This could mean that Z reacts in a step after the rate determining step, making it a subsequent step reaction intermediate. Therefore, choice B is the best answer.

For the Reaction X2 + Y + Z →\rarr→ XY + XZ, It Is Found That the Rate Equation
