# the hydrolysis of ester was carriecout separately with0.05M HCl and 0.05M H2SO4.which one of the following is true and why?
a)K(HCl)>K(H2SO4)
b)K(HCl)>K(H2SO4)
C)K(HCl)=K(H2SO4)
d)K(HCl)=0.5K(H2SO4)

Expert Answer:

###
Correct option : k_{HCl} < k _{H2SO4}

For hydrolysis of an ester k_{app} = k_{true} [H^{+}]

Since [H_{+}] in HCl is smaller than in H_{2}SO_{4}.

It follows that (k_{app})_{HCl} <(k_{app})_{H2SO4}

Correct option : k_{HCl} < k _{H2SO4}

For hydrolysis of an ester k_{app} = k_{true} [H^{+}]

Since [H_{+}] in HCl is smaller than in H_{2}SO_{4}.

It follows that (k_{app})_{HCl} <(k_{app})_{H2SO4}
