Which statement is not true for a second-order reaction? (a) It can have rate constant

1\times10^{-2}\text{ L mol}^{-1}\text{ s}^{-1}

. (b) Its half-life is inversely proportional to its initial concentration. (c) The time to complete

75\%

reaction is twice the half-life. (d)

T_{50\%}=\frac{1}{k\times\text{initial concentration}}
