The time required for 100% completion of a zero order reaction is

Options

A. ak
B. `(a)/(2k)`
C. `(a)/(k)`
D. `(2k)/(a)`

Answer

C

Explanation

For a zero order reaction,
`(dx)/(dt)=krArrdx=k" dt"`
`rArr" "overset(x)underset(o)intdx=overset(t)underset(o)intk" dt"rArrx=kt`
For 100% completion of the reaction ,a=ktort=a//k
