$C{{H}_{3}}-\underset{C{{H}_{3}}}{\mathop{\underset{|\,\,\,\,\,}{\mathop{\overset{OH}{\mathop{\overset{|\,\,\,\,}{\mathop{C-}}\,}}\,}}\,}}\,C{{H}_{2}}-\underset{C{{H}_{3}}\,}{\mathop{\underset{|\,\,\,\,\,\,\,}{\mathop{CH-}}\,}}\,C{{H}_{3}}$
$ + \frac{1}{2}\frac{{d\left[ C \right]}}{{dt}} = - \frac{1}{3}\frac{{d\left[ D \right]}}{{dt}} = + \frac{1}{4}\frac{{d\left[ A \right]}}{{dt}} = \frac{{ - d\left[ B \right]}}{{dt}}$
the reaction is
$AB \to$ Isothermal expansion
$AC \to$ Adiabatic expansion
Which of the following options is not correct ?
