Question: what is the difference between degree of dissociation?
Answer: The degree of dissociation of a substance is defined as the fraction of its molecules dissociating at a given time. ... 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.
