Under the same reaction conditions, the intial concentration of `1.386 mol dm^(-3)` of a substance becomes half in `40 s` and `20 s` theough first order and zero order kinetics, respectively.
The ratio `(k_(1)//k_(0))` of the rate constants for first order `(k_(1))` and zero order `(k_(0))` of the reaction is

B. ` 1.0 mol " " dm^(-3)`
C. ` 1.5 mol " " dm^(-3)`
D. ` 1.5 mol^(-1) " " dm^(3)`

Answer
