Answer:
Initial rate of a first order reaction =kC
=1×10−2×1.0=1×10−2 mol L−1 s−1
Explanation:
Concentration after 60 seconds is calculated by applying first order kinetic equation,
k=602.303log10(1−x)1
or 1×10−2=602.303[−log(1−x)]
or 2.30360×10−2=−log(1−x)=0.2605
log(1−x)=−0.2605=1ˉ.7395
(1−x)= antilog of (1ˉ.7395)=0.5489 mol L−1
Rate of reaction after 1 minute =k×C
=1×10−2×0.5489
=5.489×10−3 mol L−1 s−1
