1. What is the change in entropy (J/K-mol) for the universe of the above reaction at 25 oC ?

Question

In this equation, the minimum kelvin temperature the system must be heated to to make the below reaction product favored is 980.1136:

C (graphite) + CO2 (g) → CO (g)

1. What is the change in entropy (J/K-mol) for the universe of the above reaction at 25 oC ?

2. For the same reaction, what is the maximum useful work (kJ) that can be performed on the surroundings from the production of 3.9 moles of CO (g) ??

any help would be greatly appreciated!!!

Answer 1

USe Gibbs Helmholtz eqn.
