Kinetic of acidic hydrolysis of ester is a pseudo Ist order reaction
`CH_(3)COOCH_(3)(aq)+H_(2)_(excees)(l)`
`overset [H^(+)] rarr CH_(3)COOH(aq) + CH_(3)OH(aq)`
Rate law is given by `r=K[H^(+)][H_(2)O][CH_(3)COOCH_(3)]`
`K=1.8xx10^(-3)M^(-2)sec^(-1)` where `H^(+)` ion concentration is given by acid catalyst in an experiment 1 M `CH_(3)COOCH_(3)` is hydrolyscd using `0.1` M HCI as catayst.
Calculate the time at which ester concentration reduce to `0.25` M `[l n2=0.7]` (Given Density of pure `H_(2)O=1 gm //ml)`
A. 70 sec
B. 140 sec
C. `700/9` sec
D. `350/9` sec
