(N/A) $1.$ The ratio of concentration of products to concentration of reactants is the $\text{reaction quotient } (Q_c)$ or $\text{equilibrium constant } (K_c)$ at equilibrium.
$2.$ $\ln(\log(x))$ is a mathematical expression and does not simplify to a standard constant; it remains $\ln(\log(x))$.
$3.$ At equilibrium,the cell potential $E_{cell}$ is zero. The relationship is $E_{cell} = E_{cell}^{o} - \frac{RT}{nF} \ln(K_c)$,and at equilibrium,$E_{cell} = 0$.
