Consider the data given below for the reaction $\text{A} + \text{B} \longrightarrow \text{Product}$
Answer the following questions.
| S.No. | conc. of [A] $\text{mol L}^{-1}$ | conc. of [B] $\text{mol L}^{-1}$ | Rate; $\text{mol L}^{-1}\text{sec}^{-1}$ |
|---|---|---|---|
| 1. | $0\cdot1$ | $0\cdot1$ | $4\cdot0 \times 10^{-4}$ |
| 2. | $0\cdot2$ | $0\cdot2$ | $1\cdot6 \times 10^{-3}$ |
| 3. | $0\cdot5$ | $0\cdot1$ | $1\cdot0 \times 10^{-2}$ |
| 4. | $0\cdot5$ | $0\cdot5$ | $1\cdot0 \times 10^{-2}$ |
(i)[1.0]
What is the order of reaction with respect to A and B?
(ii)[1.0]
Calculate the rate constant.
(iii)[1.0]
Determine the reaction rate when the concentration of A and B are $0\cdot2\text{ mol L}^{-1}\text{sec}^{-1}$ and $0\cdot35\text{ mol L}^{-1}\text{sec}^{-1}$ respectively.
