Calculate the overpotential for the reduction reaction of Ag+ to Ag on a silver electrode at 25°C with a current density of 0.5 A/cm2. The standard reduction potential of Ag+ to Ag is 0.799 V vs. the standard hydrogen electrode. The activation energy for this reaction is 65.0 kJ/mol, the transfer coefficient is 0.4 and the reaction order is 1.5.

A chemistry student wants to buffer a solution with a pH of 4.5. The student adds 0.1 mol of a weak acid buffer to 0.1 mol of a conjugate base. Taking the pKa value of the buffer into consideration, determine how much stronger an acid in the same buffer system would need to be added to the solution to shift the pH from 4.5 to 4.0, assuming temperature and pressure are constant.
