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.

Answer»

RATE const may be taken as the measure of DEGREE of ionization of one acid used as catalyst.
HX is a stonger acid than HY, RELATIVE strength being 1.7
HX is a weaker acid than HY, their relative strength being 0.7
HX is a stronger base than HY.

Solution :`(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`
