For a hypothetical reaction `R rarr P` the rate constant is `2944.06 s^(-1)` if the concentration of R is reduced to half then the value of rate constant is

Options

A. `1472.03 s^(-1)`
B. `2944.06 s^(-1)`
C. `294.406 s^(-1)`
D. `29.4406 s^(-1)`

Answer

B

Explanation

From the units of rate constant `(s^(-1))`, the reaction is of first order. For a first order reaction `t_(1//2)` is independent of initial concentration.
