Hydrolysis of an ester is catalysed by H+ ion.
Using equimolar concentrations of two acids HX and HY, both being strong acids, the rate constants of the reaction are found to be 3 × 10–3 min–1 and 5 × 10–3 min–1 respectively at a fixed temperature. It can be concluded that
Using equimolar concentrations of two acids HX and HY, both being strong acids, the rate constants of the reaction are found to be 3 × 10–3 min–1 and 5 × 10–3 min–1 respectively at a fixed temperature. It can be concluded that
- Rate constant may be taken as the measure of degree of ionization of the acid used as catalyst
- HX is a stronger acid than HY, their relative strength being 1.7
- HX is a weaker acid than HY, their relative strength being 0.6
- none is correct
Answer
(A) Rate constant may be taken as the measure of degree of ionization of the acid used as catalyst, (C) HX is a weaker acid than HY, their relative strength being 0.6
