5. Complete the table below for the four different combinations of enthalpy and entropy. G at low T | AG at high T | Is the spontaneity (circle one) (circle one) temperature dependent? (circle one) Yes No Yes No Yes No Yes No 0 0 6. Write the complete balanced formation reaction for theobromine (CHeN402), a compound found in chocolate. Hint: The standard state for carbon is graphite. Use the given ÎH·S" and ÎGãf values to calculate the ÎG'm at 25°C for the following reaction two different ways. First with the ÎH'm and AS"m to get AG'm and then with ÎGis to get ÎG'm. Compare your results. 7. | cs2(g) + 1 2H20(a 202(g) 2503(g) | CH4(g) + â AH° (kJmol) 117 S (J/mol K) 238 AG (kJ/lmol)67 -286 70 -237 75 186 51 -396 205 257 -371
