Consider the reaction scheme for degradation of water 1 atm: Reaction 1: H20 ↔ H2 + 1/2 O2 Reaction 2: H20 ↔ 1/2 H2 + OH Delta G1 = 228,566 kJ/kmol Delta G2 = 263.270 kJ/kmol Delta Hr,1° = 241,820 kJ/kmol Delta Hr,2° = 281,280 kJ/kmol A) Calculate the value of the equilibrium constant for each Reaction at 25°C. What does this tell you about the equilibrium composition B) Estimate the equilibrium constant for each reaction at 5,000°C. C) Fully set up and explain how you would solve for the equilibrium composition of reaction mixture which started with 1 mole of water. Include an expression for the equilibrium constant(s) in terms of composition as part of your answer.

Question
Consider the reaction scheme for degradation of water 1 atm:
Reaction 1:
H20 ↔ H2 + 1/2 O2
Reaction 2:
H20 ↔ 1/2 H2 + OH
Delta G1 = 228,566 kJ/kmol
Delta G2 = 263.270 kJ/kmol
Delta Hr,1° = 241,820 kJ/kmol
Delta Hr,2° = 281,280 kJ/kmol
A) Calculate the value of the equilibrium constant for
each Reaction at 25°C. What does this tell you about the equilibrium composition
B) Estimate the equilibrium constant for each reaction at 5,000°C.
