Methanol, CH3OH, can be made by the reaction of CO with H2: Co(g) + 2H2(g) = - CH3OH(g) AH° = -90.7 kJ and AS° = -90.88 JK-1 for this reaction. How is AG° for the reaction expected to vary with increasing temperature? Under standard conditions, is the reaction spontaneous at 298 K? Explain. Select one: O a. AG° will increase; the reaction is spontaneous at 298 K, since AG° < 0 at 298 K. O b. AG° will decrease; the reaction is spontaneous, since AG° < 0 at 298 K. O c. AG° will increase; the reaction is not spontaneous, since AG° < 0 at 298 K. d. AG° will decrease; the reaction is not spontaneous, since AG° > 0 at 298 K. e. AG° will increase; the reaction is not spontaneous, since AG° > 0 at 298 K.
