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 eb `3xx10^(-3)"min"^(-1)` and `5xx10^(-3)"min"^(-1)` respectively at a fixed temperature. It can be concluded that.

Options

A. Rate const may be taken as the measure of degree of ionization of one acid used as catalyst.
B. HX is a stonger acid than HY, relative strength being 1.7
C. HX is a weaker acid than HY, their relative strength being 0.7
D. HX is a stronger base than HY.

Answer

A, C

Explanation

`(st(Hx))/(st(Hy))=sqrt((K_(a1))/(K_(a2)))=sqrt((K_(C_(1)))/(K_(C_(2))))=sqrt((3xx10^(-3))/(5xx10^(-3)))=sqrt(0.6/1)=0.77`
