Statement A :
A negative value of \(\mathrm{E^{\circ}}\) means that the redox couple is weaker reducing agent than the \(\mathrm{\mathrm{H}^{+} / \mathrm{H}_{2}}\) couple.
Statement B :
A negative \(\mathrm{\mathrm{E}^{\circ}}\) means that the redox couple is stronger reducing agent than the \(\mathrm{\mathrm{H}^{+} / \mathrm{H}_{2}}\).
