Question

How degree of dissociation is equal to x/4

Answer 1

Answer:

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.
