Half-lives of a first order and a zero order reaction are same. Then the ratio of the initial rates of first order reaction to that of the zero order reaction is (a) 0.693
B.2 0.693✓ Correct
C.0.693
Explanation
For first order reaction, 0 0 1/2 0 0 0 1/2 0.693 Rate kA A t A For zeroorder reaction,Rate kA 2t Ratioin rates 2 0.693 x
