For each of the following reactions, calculate ΔH∘rxn, ΔS∘rxn, ΔG∘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?
a) 2CH4(g)→C2H6(g)+H2(g)
b) 2NH3(g)→N2H4(g)+H2(g)
c) N2(g)+O2(g)→2NO(g)
d) 2KClO3(s)→2KCl(s)+3O2(g)
Can you please show equations. I am having so much trouble with these.
