Document Summary
Iii rxn= 90. 79 kj/mol, so: consider the following reaction: 2 hg(l) + o2(g) 2 hgo(s); ho. At 25oc hbro dissociates in water with a ka = 2. 3x10-9. Is this dissociation a spontaneous process when [h3o+] = I: pt | h2(g) | h+(aq) || cu2+(aq) | cu(s) Ii: na(s) | na+(aq) || k+(aq) | k(s) Iii: fe(s) | fe2+(aq) || zn2+(aq) | zn(s) (1) i only (3) iii only (5) ii and iii (4) i and ii (2) ii only. I: the electrode in the anode gains mass. Ii: na+(aq) flows from the salt bridge into the half-cell containing clo3. Iii: electrons move from the half-cell containing clo3 (1) i only (2) ii only (3) i and ii. /cl to the half-cell containing ni/ni2+ (4) ii and iii (5) i and iii: what is the value for the standard free energy of the following reaction:
