1. The problem statement, all variables and given/known data Estimate ΔG for the process where one mol of ideal gas is subjected to an increase in pressure from 1.00 atm to 11.0 atm at 25.0°C. 2. Relevant equations ΔG=ΔH-TΔS ΔH=C(p,m)(Tf-Ti 3. The attempt at a solution Seems straight forward, but it seems i am not given enough information to complete the problem. I need C(p,m)? It does say estimate. Does that mean that i only need to imply that the Gibbs free energy will be possitive, negative, or 0? If you can help me clarify the problem that would be greatly appreciated! Thanks.
