$A.$ The electrical work that a reaction can perform at constant pressure and temperature is equal to the reaction Gibbs energy.
$B.$ $E _{\text {cell }}^0$ is dependent on the pressure
$C.$ $\frac{ dE ^0 \text { cell }}{ dT }=\frac{\Delta_{ r } S ^0}{ nF }$
$D.$ A cell is operating reversibly if the cell potential is exactly balanced by an opposing source of potential difference.
$\frac{{ - d[A{B_5}]}}{{dt}} = K[A{B_5}]$ ; $\frac{{d[B]}}{{dt}} = {K_1}[A{B_5}]$
So the correct relation between $K$ and $K_1$ is

$(I)$ $CO_2$ $(II)$ $Br_2$ $(III)$ $SnCl_2$ $(IV)$ $HF$ $(V)$ $NMe_3$
