Point out the wrong statement:
For a first order reaction
(a) time for half-change \( \left(\mathrm{t}_{1 / 2}\right) \) is independent of initial concentration
(b) change in the concentration unit does not change the rate constant \( (\mathrm{k}) \)
(c) time for half-change \( \times \) rate constant \( =0.693 \)
(d) the unit of \( \mathrm{k} \) is \( \mathrm{mole}^{-1} \mathrm{~min}^{-1} \)
