Half lives and initial concentration of a first
order and zero order reactions are same. Then
the ratio of the initial rates of the first order
reaction to that of zero order reaction is :-
(1) 170.693
(2) 2 x 0.693
(3) 2/0.693
(4) 6.93

Answer:
2*0.693
Explanation:
t1/2 of 1st order =t1/2of 2nd order
0.693/k=[A]/2k" (k =rate constant for 1st order
k"= rate constant for zero order )
k/k"=2*0.693/[A]......eqn 1
therefore, r/r"=K[A]'/k" (since both have sameinitial concentration )
=2*0.693(from eqn 1)
