use the data below to calculate ΔG at 245 K for each of the following reactions.
Then use the data in the chart to determine whether each reaction is spontaneous at 245 K. 

Compound ΔG°f (kJ/mol) ΔH°(kJ/mol) ΔS°f (J/mol·K)
 H2S(g)  -33.01  -20.17  205.6
 O2(g)  0  0  205.0
 H2O(g)  -228.6  -241.8  188.7
 SO2(g)  -300.1  -296.8  248.2
 SO3(g)  -371.1  -395.7  256.8
 H2SO4(l)  -690.0  -814.0  156.9
 S(g)  236.7  277.2  167.8
 H2O(l)  -237.2  -285.8  70.0


2SO2​(g)+O2​(g) --> 2SO3​(g)

ΔG245  =  ___ kJ
