Free Energy vs. Rate?
I know that spontaneity (negative free energy. negative delta G) do not necessarily mean that the rate is fast. But if the negative delta G value is large, thus, K is large, can you assume the process is fast? Why or why not?

Chemistry question involving Free energy and enthropy?
The question first asked for the equation that relates free energy, entropy and enthalpy change of a chemical reaction and I did:
(delta)G = (delta)H – T(delta)S
Than it asked to use that equation to explain why the endothermic dissolution (+4kJ/mol) of crystalline sodium chloride in water is spontaneous at room temperature.
I can’t figure this out?
Please help. Thanks
