The relationship between rate constant and half life period of zero order reaction is given by _______.

Options

A. `t_(1//2)=[A]_(O)2k`
B. `t_(1//2)=(0.693)/(k)`
C. `t_(1//2)=([A]_(O))/(k)`
D. `t_(1//2)=([A]_(O))/(2k)`

Answer

C

Explanation

The relationship between rate constant (k) and half-life period of zero order reaction is written as,
`k=([A]_(0)-[A])/(t_(1//2))`
`or " " k=([A]_(0)-1//2[A]_(0))/(t_(1//2))" "[because at" "t_(1//2),[A]=1/2[A]_(0)]`
`or" "t_(1//2)=[A]_(0)/(2k)`
