Question

Initial concentration of reactant of Zero order reaction is 0.04 M, rate constant of the reaction is `1.2xx10^(-3) mol dm^(-3) sec^(-1)` . Hence the half life time is
A. `57.75`sec
B. `16.66 sec `
C. `33.33 sec `
D. `5.77 sec`

Answer 1

Correct Answer - B
`t_(1//2) =([A_(0)])/(2K)=(0.04)/(2xx1.2xx10^(-3))`
