Question

'$n$' mole of a reactant '$A$' gives one mole each of $B$ and $C$ in reversible reaction. If degree of dissociation of '$A$' is independent of initial concentration of '$A$' then '$n$' is:

Answer 1

$n$ moles $\left[A\right]\to 1$ moles $\left[B\right]+1$ moles $\left[C\right]$

since, rate is independent of initial concentration, the order of section is zero.

As $k$ value is not given, finding the initial concentration is not possible numerically and initial concentration will depend on the mdecularity of the reaction.

Hence $n$ is $2.\Rightarrow$ the value of $n$ is $2$

e.g., $2HI\to H_2+I_2$ for a bindecular reaction.
