ANSWER :

Degree of Dissociation

The degree of dissociation of a substance is defined as the fraction of its molecules dissociating at a given time.

Let us consider the reaction,

2NH3 (g) \rightleftharpoons N2 (g) + 3H2 (g)

Let the initial moles of NH3(g) be ‘a’. Let x moles of NH3 dissociate at equilibrium.

Degree of dissociation (a) of NH3 is defined as the number of moles of NH3 dissociated per mole of NH3.

if x moles dissociate from ‘a’ moles of NH3, then, the degree of dissociation of NH3 would be x/a.
