The value of rate constant of a pseudo first order reaction……

Answer»

depends on the CONCENTRATION of REACTANTS PRESENT in SAMLL amount
depends on the concentratin of reactants present in excess
is INDEPENDENT of the concentration of reactants
depends only on temperature.

Solution :The reaction of hydrolysis of ethyl acetate is as follows.
`CH_(3)COOC_(2)H_(5)+underset("Excess")(H_(2)O)overset(H^(+))to`
`CH_(3)COOH+C_(2)H_(5)OH`
This reaction is pseudo first order and its rate does not depends on`H_(2)O` as the concentration of `H_(2)O` remain almost constant.
Rate=K`[CH_(3)COOC_(2)H_(5)]`
Where ,k=`k_(1)[H_(2)O]`=constant
In this way the reactant of first order depends on the reactant which is in less proportion.
So (A) is correct.
