Chemical Kinetics And Nuclear Chemistry

Under the same reaction conditions, initial concentration of 1.386 mol dm\(^{-3}\) of a substance becomes half in 40 seconds and 20 seconds through first order and zero order kinetics, respectively. Ratio \(\left( {{{{k_1}} \over {{k_0}}}} \right)\) of the rate constants for first order (\(k_1\)) and zero order (\(k_0\)) of the reactions is:
