Reactant 'A' (initial concentration, a) reacts according to zero order kinetics, the time takews for the completion of the reaction is

Options

A. `k//a`
B. `a//2k`
C. ka
D. `2k//a`

Answer

C

Explanation

For zero order reaction, `k=(1)/(t){[A]_(0)-[A]}`
When reaction is complete `[A]=0`
`:.k=([A]_(0))/(t)=(a)/(t)or t=(a)/(k)`.
