A disproportionation reaction involves a substance that acts as both an oxidizing and reducing agent, producing higher and lower oxidation states of the same element in the products. Which of the following disproportionation reactions are spontaneous under standard conditions? Calculate ΔG° and K at 25°C for those reactions that are spontaneous under standard conditions. Use the following half-reactions. (Enter ΔG° = 0 and K= 0 for reactions that are not spontaneous.) ClO3- + 3 H+ + 2e- → HClO2 + H2O ℰ° = 1.21 VHClO2 + 2 H+ + 2e- → HClO + H2O ℰ° = 1.65 V (a) 2 Cu+(aq) → Cu2+(aq) + Cu(s) spontaneous or not spontaneous ? ΔG° -34.7 kJ K ? I found that G is correct and because it is negative it is spontaneous. Could you please help me figure out K?

Question
A disproportionation reaction involves a substance that acts as both an oxidizing and reducing agent, producing higher and lower oxidation states of the same element in the products. Which of the following disproportionation reactions are spontaneous under standard conditions? Calculate ΔG° and K at 25°C for those reactions that are spontaneous under standard conditions. Use the following half-reactions. (Enter ΔG° = 0 and K= 0 for reactions that are not spontaneous.)
ClO3- + 3 H+ + 2e- → HClO2 + H2O ℰ° = 1.21 V
HClO2 + 2 H+ + 2e- → HClO + H2O ℰ° = 1.65 V
HClO2 + 2 H+ + 2e- → HClO + H2O ℰ° = 1.65 V
(a) 2 Cu+(aq) → Cu2+(aq) + Cu(s)
spontaneous or not spontaneous ?
| ΔG° | -34.7 kJ |
| K | ? |
I found that G is correct and because it is negative it is spontaneous. Could you please help me figure out K?
