Match the Variation of Reaction Spontaneity (Sign of ΔG) given in Column I with the Signs of ΔH and ΔS given in column II.

COLUMN I	COLUMN II
	ΔH	ΔS	ΔG = ΔH – TΔS
1.	−	+	a. The reaction is both enthalpically and entropically opposed. It is nonspontaneous (endergonic) at all temperatures.
2.	−	−	b. The reaction is enthalpically opposed (endothermic) but entropically favored. It is spontaneous only at temperatures above T = ΔH/ΔS.
3.	+	+	c. The reaction is enthalpically favored but entropically opposed. It is spontaneous only at temperatures below T = ΔH/ΔS.
4.	+	−	d. The reaction is both enthalpically favored (exothermic) and entropically favored. It is spontaneous (exergonic) at all temperatures.
