What is pseudo-first order reaction? Give an example.

Explanation

A reaction which seems to be higher order, but follows first order kinetics is called psuedo first order reaction.
Example:
(1) Acid hydrolysis of methyl acetate
`CH_(3)COOCH_(3) + H_(2)O overset("H^(+)")(to) CH_(3)COOH + CH_(3)OH`
(2) Inversion of cane sugar
`C_(12)H_(22)O_(11) + H_(2)O overset("H^(+)")to C_(6)H_(12)O_(6) + C_(6)H_(12)O_(6)`
