(A) Standard hydrogen electrode $(SHE)$ is a primary reference electrode.$SHE$ is represented by $Pt_{(s)} | H_{2(g)} | H^{+}_{(aq)}$ and is assigned a potential of $0.00 \ V$ at all temperatures.It serves as the fundamental standard for measuring electrode potentials of other half-cells.The half-cell reaction is: $H^{+}_{(aq)} + e^- \rightarrow \frac{1}{2} H_{2(g)}$
