Consider the electrochemical cell Pt(s) | Cut, Cu2+ (1 M) || H* (1 M), H₂ (g. 1 atm) | Pt(s). Which of the following is correct about AG, K and spontaneity of the redox reaction as it is written for this cell at 25 °C: a) AG = 29.0 kJ, k is about 8 x 10-6, and it is NOT spontaneous. b) AG-29.0 kJ, K = 1 × 10-5, and it is spontaneous. O AG-14.5 kJ, K = 340, and it is NOT spontaneous. c) d) AG = 29.0 kJ, K = 9 × 10-27, and it is spontaneous.. e) AG 14.5 kJ, K = 0.0029, and it is spontaneous.
