Derive an expression for half life period of a zero order reaction.

Explanation

Half life period of a zero order reaction.
At `t=t_(1//2),[R]=([R]_0)/(t)`
`k=(1)/(t_(1//2))[R]_0-([R]_0)/(2)`
or `t_(1//2)=(1)/(k)[[R]_0-[R]_0)/(2)=([R]_0)/(2k)`
Thus half life, `t_(1//2)` of a zero order reaction is directly proportional to the initial concentration of the reactants and inversely proportional to the rate constant.
