Question

The rate law for the reaction $2X+Y\to Z$ is Rate $=A[X][Y1$. The correct statement with regard to this relation is

• A. The unit of $k$ is $s^{-1}$
• B. The rate of the reaction is independent of $[X]$ and $[Y]$
• C. For this reaction $t_{1/2}$ is independent of initial concentrations of reactant
• D. The rate of formation of $Z$ is twice the rate of disappearance of $X$
• E. The rate of disappearance of $X$ is equal to rate of disappearance of $Y$

Answer 1

Answer: (D)

Correct answer is (d) The rate of formation of $Z$ is twice the rate of disappearance of $X$
