For a hypothetical reaction, `ArarrP`
the rate constant is 0.12 `s^(-1).` which of the following relation is correct, if `[R]_(0)` is the initial concentration?
A. `t_(1//2)=([R]_(0))/(0.12xx12)`
B. `t_(1//2)=(3)/(2(0.12)[R]_(0)^(2))`
C. `t_(1//2)=(0.693)/(0.12)`
D. `t_(1//2)=(0.693)/(0.12xx3)`

Correct Answer - C
Since, the unit of rate constant is `sec^(-1)`. Thus, the order of the reaction is 1. Hence , `t_(1//2)=(0.693)/(0.12).`
