For each of the following reactions, calculate ?H?rxn, ?S?rxn, ?G?rxn at 25?C. State whether or not the reaction is spontaneous. If the reaction is not spontaneous, would a change in temperature make it spontaneous? If so, should the temperature be raised or lowered from 25?C?

2CH4(g)?C2H6(g)+H2(g)

?H?rxn, ?S?rxn, ?G?rxn at 25?C???
