Question 1

If a constant current of 4.5 amperes is passed through a cell containing Cr³⁺ for 1.0 hour, how many grams of Cr will plate out onto the cathode? (The atomic mass of Cr is 51.996.)

◦ 8.7 g
◦ 8.1 × 10^–4 g
◦ 2.9 g
◦ 26 g
◦ 5.6 × 10^–2 g

Question 2

If a reducing agent M reacts with an oxidizing agent N⁺ to give M⁺ and N, and the equilibrium constant for the reaction is 1.9, then what is the E° value for the oxidation-reduction reaction?

◦ 0.016 V
◦ –0.016 V
◦ 0.0082 V
◦ –0.0082 V
◦ 0.033 V
