8. [Ch. 20] Chlorine dioxide (CIO) is produced by the reaction 2NaCIO:(aq) + Cl;(g) → 2C1O:(g) + 2NaCl(aq). Using data from the Table of Standard Reduction Potentials (given below), find E° and also AG at 25 °C for the production of CIO₂.

Consider a cell that uses the redox reaction: 3 Na (s) + La3+ (aq) → 3 Na+ (aq) + La (s). Calculate the equilibrium constant (K) for this reaction at 25 ºC, given the following standard reduction potentials: La3+ (aq) + 3 e- →  La (s)     E° = -2.37 V Na+ (aq) + e- → Na (s)         E° = -2.71 V       1.8 x 10-6     5.7 x 10-18     5.6 x 105     1.7 x 1017
