Document Summary

2017 exam solutions: create an ice table to solve for the equations required for each entity to reach equilibrium. The total pressure at equilibrium will be equal to the sum of these equilibrium equations. Finally, use the keq equation to solve for k: use the standard keq equation (products/reactants) to solve for k, the concentration is higher inside the cell than outside the cell. To find the potential difference across the membrane, use the nernst equation. For the e cell entity of the equation, note that the reaction will proceed from k+ concentrated . The q entity is going to be [concentration dilute] / [concentrate concentrated]. Note that n=2 for this reaction, because 2 electrons are transferred in each half-cell reaction: the cathode for this reaction is ce. 0. 25v, n=2, and ln q is the [ce3+]2/ [ce4+]2[cl-]2: the cathode is silver based on the cell potentials (it has a higher voltage).
