Answer»

In
a pseudo first order hydrolysis of ester in water, the following
results were obtained:

t/s	0	30	60	90
[Ester]mol L⁻¹	0.55	0.31	0.17	0.085

(i) Calculate
the average rate of reaction between the time interval 30 to 60
seconds.

(ii)
Calculate
the pseudo first order rate constant for the hydrolysis of ester.
