Which of the following statement is NOT true for a reaction having rate law $\mathrm{r}=\mathrm{k}\left[\mathrm{H}_2\right]\left[\mathrm{I}_2\right]$ ?
  1. The reaction is first order in $\mathrm{H}_2$
  2. Overall order of reaction is 1
  3. The reaction is first order in $\mathrm{I}_2$
  4. Overall order of reaction is 2

Solution

$\mathrm{r}=\mathrm{k}\left[\mathrm{H}_2\right]\left[\mathrm{I}_2\right]$ Overall order of reaction is 2. Order of reaction wrt $\mathrm{H}_2$ is 1 and Order of reaction wrt $I_2$ is 1.
