For a first order reaction `t_0.75` is 277.2sec. Its specific rate constant in `s^-1` is -:

For a first order reaction, t_(0.75) is 1386 seconds, then the specific rate constant in sec^(-1) is

For a first order reaction t_(0.75) is 1386 s . Therefore, the specific rate constant is

Half life period of a first order reaction is 693 seconds. The specific rate constant of the reaction is

Half life period of a first - order reaction is 1396 seconds. The specific rate constant of the reaction is

Half-life period of a first-order reaction is 1386 seconds. The specific rate constant of the reaction is

The half-life period of a first order reaction is 100 sec. The rate constant of the reaction is

Assertion : For a first order reaction, t_(1//2) is indepent of rate constant. Reason : For a first reaction t_(1//2) prop [R]_(0) .
