Problem

The rate constant for the first order decomposition of a certain reaction is given by the equation,

\ln K(\text{sec}^{-1}) = 14.34 - \frac{1.25 \times 10^4}{T}

Calculate : (a) the energy of activation. (b) the rate constant at

500 \text{ K}

. (c) at what temperature will its half-life period be 256 minute? (IIT July 1997)
