A) \[\text{ }\!\!\Delta\!\!\text{ G}\] and \[\text{ }\!\!\Delta\!\!\text{ H}\] should be negative
B) \[\text{ }\!\!\Delta\!\!\text{ G}\]and \[\text{ }\!\!\Delta\!\!\text{ H}\]should be positive
C) \[\text{ }\!\!\Delta\!\!\text{ G = }\!\!\Delta\!\!\text{ S = 0}\]
D) \[\text{ }\!\!\Delta\!\!\text{ H }\!\!\Delta\!\!\text{ G}\]
Correct Answer: A
Solution :
\[\Delta G=\Delta H-T\Delta S\] For a reaction to be spontaneous \[\Delta G\] must be negative. If \[\Delta G\] and \[\Delta H\] are negative, then reaction will be spontaneous at all temperature.
