Which of the following processes is endothermic? a) H2O (g) --> H2O (l) b) 3O2 (g) + 2CH3OH(g) --> 2CO2(g) + 2H2O(g) c) H2O (s) --> H2O (l) d) O2(g) + 2H2(g) --> 2H2O(g) I a guessing b, since energy has to go into the reaction for water to go from a solid to a liquid.

Chemistry
2CO(g) + O2(g) 2CO2(g) Go = -511.6 kJ and So = -173.1 J/K at 314 K and 1 atm. The maximum amount of work that could be done by this reaction when 2.43 moles of CO(g) react at standard conditions at this temperature is__________ kJ. how?!
