Question: Consider a carbon electrode with a circular shape and a diameter of (3.0 mathrm{~mm}) dipping into a (0.1 mathrm{M} mathrm{NaCl}) solution with a double layer

Consider a carbon electrode with a circular shape and a diameter of $3.0 \mathrm{~mm}$ dipping into a $0.1 \mathrm{M} \mathrm{NaCl}$ solution with a double layer capacitance of $20 \mu \mathrm{F} / \mathrm{cm}^{2}$. If the electrode receives a pulse of $1.0 \times 10^{12}$ electrons, what will the change in voltage be at the electrode solution interface.
