Question

If put a piece of solid cadmium into a 1 M tin chloride solution at room temperature describe each of the following quantities for the reaction Sn^4+ (aq)+Cd (s) Sn^2+ (aq) + Cd^2+ (aq). Use only the answer choices listed in bold and use the one that is the most informative descriptor of the quantity (if K > 1 and K > 0 would both be true choose the one that communicates the most useful information) Allowed answer choices for Delta G degree, E degree K, Delta G, E: = 0 0 = 1 1 Allowed answer choices for Q: = K, >K

Explanation / Answer

For the given electrochemical cell,

                                   dGo          dG            dEo            E             Q              K

Initial conditions          <0            <0              >0             >0           <1            <Kf       

At equilibrium              <0            =0              >0             >0           >1            >Kf
