Entropy

The entropy for a spontaneous reaction may be positive or negative. The free energy change must be negative. As ΔG=ΔH-TΔS, a positive TΔS can be overcome by a negative ΔH. Note also that equilibrium constants refer to the standard free energy change. Petergans (talk) 08:51, 26 February 2011 (UTC)
