## Document Summary

If the solution is basic, add oh- to each side to react with h+s. Provides a surface for the dissociation and oxidation of h2 molecule. From electrochemistry: e cell > 0 (+: e (v) = (cid:2926)(cid:2925)t(cid:2915)(cid:2924)t(cid:2919)al (cid:2915)(cid:2924)(cid:2915)r(cid:2917)y (cid:2914)(cid:2919)(cid:2916)(cid:2916)(cid:2915)r(cid:2915)(cid:2924)(cid:2913)(cid:2915) (cid:4666)j(cid:4667) (cid:2913)(cid:2918)ar(cid:2917)(cid:2915) (cid:4666)c(cid:4667, charge = q. < 1 reactants favored: connecting e cell and k spontaneous. Not spontaneous: e cell = (cid:1814)(cid:1812)(cid:1814)(cid:1785, non-standard conditions, at standard conditions: e cell = (cid:2777).

Exam 3 chemistry short study guide: at all temps: e = e cell - (cid:1814)(cid:1812)(cid:1814)(cid:1791, at 298 k: e= e cell - (cid:2777).
