Determine the minimum kelvin temperature the system

Question

1. Determine the minimum Kelvin temperature the system must be heated to make the below reaction product favored?
C (graphite) + 2H₂O (l) → CH₃COOH(l)

2. Determine the change in entropy (J/K-mol) for the universe of the above reaction at 25 ^oC

3. Determine the maximum useful work (kJ) that can be performed on the surroundings from the production of 3.5 moles of CH₃COOH (l) for the same reaction.
