Question 1

Consider a voltaic cell based on the following cell reaction:
Ni(s) + At₂(s) → Ni²⁺(aq) + 2At^–(aq)
Given that the standard cell emf is 0.55 V, what is the standard reduction potential for astatine? [E°(Ni²⁺/Ni) = –0.25 V]
◦ 0.80 V
◦ 0.30 V
◦ –0.30 V
◦ –0.80 V
◦ 0.43 V

Question 2

Consider an electrochemical cell based on the following cell diagram:
Pt | Pu³⁺(aq), Pu⁴⁺(aq) || Cl₂(g), Cl^–(aq) | Pt
Given that the standard cell emf is 0.35 V and that the standard reduction potential of chlorine is 1.36 V, what is the standard reduction potential E°(Pu⁴⁺/Pu³⁺)?
◦ 2.37 V
◦ 1.01 V
◦ –1.71 V
◦ –1.01 V
◦ 1.71 V
