Question:
The time for half life period of a certain reaction A $\longrightarrow$ Products is 1 hour, when the initial concentration of the reactant ' $\mathrm{A}^{\prime}$ is $2.0 \mathrm{~mol} \mathrm{} \mathrm{L}^{-1}$, How much time does it take for its concentration to come from $0.50$ to $0.25 \mathrm{~mol} \mathrm{} \mathrm{L}^{-1}$ if it is a zero order reaction?
Correct Option: , 4
Solution:
For zero order reaction
