A student needs to calculate the efficiency of an electrochemical cell that has a potential difference of 1.5 volts and a current of 0.5 amperes passing through it, with the help of Faraday's Law. If the electrode reaction produces chlorine gas with a Faraday efficiency of 79%, and the overall voltage efficiency of the cell is 85%, what is the efficiency of the electrochemical cell?

A student has a solution of acetic acid (CH3COOH) with a concentration of 0.1 M and wants to calculate the effect of adding sodium acetate (NaCH3COO) with a concentration of 0.05 M on the equilibrium position of the reaction CH3COOH + H2O ↔ CH3COO- + H3O+. Calculate the new equilibrium concentrations of all species and explain the effect of the added common ion on the equilibrium position.
