Question
Define degree of dissociation.
✓
Answer
Degree of dissocsavlt is defined as a fraction of total number of moles of an electrolyte that dissociate into its ions at equilibrium.
It is denoted by a and represented by,
$\begin{aligned}
& \alpha=\frac{\text { number of moles dissociated }}{\text { total number of moles of an electrolyte }} \\
& \text { OR } \alpha=\frac{\text { Per cent dissociation }}{100}
\end{aligned}$
$\therefore$ Per cent dissociation $=\alpha \times 100$

The rate law for the reaction $2 H _{2( g )}+2 NO _{( g )} \rightarrow N _{2( g )}+2 H _2 O _{( g )}$ is given by rate $= k \left[ H _2\right][ NO ]^2$. The reaction occurs in the following steps :
(i) $H _2+2 NO \rightarrow N _2 O + H _2 O$
(ii) $N _2 O + H _2 \rightarrow N _2+ H _2 O$
What is the role of $N _2 O$ in the mechanism? Identify the slow step.
