If ##ΔG_{sys} = ΔH_{sys} - TΔS_{sys}; ΔS_{sys} = \frac {-ΔH_{surr}}{T} ##
Then, doesn't this expression just simplify to:
##ΔG_{sys} = ΔH_{sys} + ΔH_{surr}## and isn't ##ΔH_{sys} = -ΔH_{surr}##?
So then ##ΔG = 0##...this does not seem correct...could anyone please clarify my mistake and the formal proof of free energy if it differs from the one I have shown?
Also, what is the explanation for why there is no free energy change during phase changes? I was merely told this without any explanation and one would be very helpful.
