From a table of potentials to log K

You will write functions that take two couples from a table and work out the emf of the cell, whether it runs as written, the Gibbs energy change and $\log K$. A cell is written with the right-hand electrode first in each call.

The idea. $E^\circ_{cell} = E^\circ_{right} - E^\circ_{left}$. Then $\Delta G^\circ = -nFE^\circ$ and $\log K = nE^\circ / 0.0591$.

Your tasks.

1. Complete cell_emf(right, left) so that it returns the standard emf in volts.
2. Complete runs_as_written(right, left) so that it returns True when the emf is positive.
3. Complete delta_g(e, n) so that it returns $\Delta G^\circ$ in kJ/mol.
4. Complete log_k(e, n) so that it returns $\log K$ at 298 K.
