Chemical Kinetics Question 3
Question 3 - 2024 (27 Jan Shift 1)
Consider the following data for the given reaction
$2 HI _{(g)} \rightarrow H _{2(g)}+I _{2(g)}$
| 1 | 2 | 3 | |
|---|---|---|---|
| $HI\left(molL^{-1}\right)$ | 0.005 | 0.01 | 0.02 |
| Rate $\left(molL^{-1} s-1\right)$ | $7.5 \times 10^{-4}$ | $3.0 \times 10^{-3}$ | $1.2 \times 10^{-2}$ |
The order of the reaction is ___________

Answer (2)
Solution
Let, $R=k[HI]^{n}$
using any two of given data,
$\frac{3 \times 10^{-3}}{7.5 \times 10^{-4}}=\left(\frac{0.01}{0.005}\right)^{n}$
$n=2$
