Which of the following is an example of a second order reaction ?

Options

A. A radioactive decay process
B. Decomposition of hydrtogen peroxide
C. Decomposition of nitrogen pentoxide
D. Alkaline hydrolysis of rthyl acetate

Answer

D

Explanation

Saponification of ethyl acctate ltbergt `CH_(3)COOC_(2)H_(5)NaOHrarrCH_(3)COONa+C_(2)H_(5)OH` is a second order reaction as it follows the rate law:
Rate `=K[CH_(3)COOC_(2)H_(5)][OH^(-)]`
A radioactive decay process follows first order kinetics. Decomposition of hydrogen peroxide `(2H_(2)O_(2)rarr2H_(2)O+O_(2))` and decompositon of nitrogen pentoxde both follow first order kinetics. `(N_(2)O_(5)(g)rarr2NO_(2)(g)+1//2O_(2)(g)`
