T+ kt[Ag 1+kt k+[Ao 34 Under the same reaction conditions, initial concentration of 1.386 mol dm of aaubstance becomes (kL halt in 40 s and 20 s through first order and zero order kinetics, respectively. Ratio of the rate ko constants for the first order k, and zero order (k) of the reaction is (a) 0.5 mol- dm (b) 1.0 mol dm3 (c) 1.5 mol dm (d) 2.0 mol dm'
