Gibbs Free Energy and Entropy
Does a negative deltaG mean that the entropy is always lower? Just wondering because the textbook says that a solid has a lower G value than a liquid or gas.

Re: Gibbs Free Energy and Entropy
for a negative delta G, the sign of delta S can be both positive or negative

Re: Gibbs Free Energy and Entropy
It doesn’t always mean that entropy is lower, you could have different sign combinations for enthalpy and entropy causing the negative delta G

Re: Gibbs Free Energy and Entropy
The sign of delta G is dependent on enthalpy, temperature, and entropy so entropy doesn't necessarily have to be negative; it depends on all three.

Re: Gibbs Free Energy and Entropy
No in that case its dependent on the Temp, enthalpy and entropy so it can be + or -.
Re: Gibbs Free Energy and Entropy
The other variable in the ghost equation also factor in whether or not delta S is positive or negative.

Re: Gibbs Free Energy and Entropy
there are a lot of variables that affect delta G, so entropy could be positive or negative
