Melting/Spontaneous Processes

[Tessa Lawler 1A]

In the textbook, it says Because the solid and liquid phases are in equilibrium at the melting point, you should expect to find that
ΔG=0 at 0.°C. Above that temperature the melting of the solid state is favored, so you should expect that ΔG will be negative at 10.°C.
Why does ΔG have to be negative just because the melting of the solid state is favored?

[Simmi Diwanji 2B]

When a system is thermodynamically favorable, it means that it has -deltaG because that indicates a spontaneous reaction is occurring. In this case, it is melting.

[Lia Inadomi 1I]

A negative delta G value shows that a reaction is spontaneous. The forward reaction in this case is melting so if delta G is negative then that is favored.

[daniella_knight1I]

Melting would be a forward reaction so delta G is expected to be negative and favorable because it is spontaneous.
