Current Question (ID: 18378)

Question:

$\text{A reaction } \text{A}_2 + \text{B}_2 \rightarrow 2\text{AB} \text{ occurs by the following mechanism:}$ $\text{A}_2 \rightarrow \text{A} + \text{A} \quad \text{.....(slow)}$ $\text{A} + \text{B}_2 \rightarrow \text{AB} + \text{B} \quad \text{.....(fast)}$ $\text{A} + \text{B} \rightarrow \text{AB} \quad \text{.....(fast)}$ $\text{Its order would be:}$

Options:

1. $3/2$
2. $1$
3. $0$
4. $2$

Solution:

$\text{2. HINT: Slow step is rate determining step.}$ $\text{Explanation: For the reaction } \text{A}_2 + \text{B}_2 \rightarrow 2\text{AB}$ $\text{A}_2 \rightarrow \text{A} + \text{A} \quad \text{.....(slow)}$ $\text{Thus, rate } \propto [\text{A}_2] \text{; } \text{A}_2 \text{ is present in the original equation.}$ $\text{Rate } = K[\text{A}_2]$ $\text{So, the order of reaction } = 1$
