Under the same reaction conditions, initial concentration of \[1.386mol/d{{m}^{3}}\] of a substance becomes half in 40 seconds and 20 seconds through first order and zero order kinetics, respectively. Ratio \[\left( \frac{{{k}_{1}}}{{{k}_{0}}} \right)\] of the rate constant for first order \[\left( {{k}_{1}} \right)\] and zero order \[\left( {{k}_{0}} \right)\] of the reaction is -
