Under the same reaction conditions, initial concentration of 1.386 mol dm −3{}^{-3}−3 of a substance becomes half in 40 seconds and 20 seconds through first order and zero order kinetics, respectively. Ratio (k1k0)\left( {{{{k_1}} \over {{k_0}}}} \right)(k0​k1​​) of the rate constants for first order (k1k_1k1​) and zero order (k0k_0k0​) of the reactions is:
  1. A
    0.5 mol −1{}^{-1}−1 dm 3{}^33
  2. B
    1.0 mol dm −3{}^{-3}−3
  3. C
