Question

the rate constant of any first order reaction is 1*10-2 s-1.if the initial concentration of the reaction is 1m, then find the final rate of the reaction.
​

Answer 1

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=602.303​log10​(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
