Question

MCQ : Answer is in a methanol - oxygen fuel cell the net reaction is as CH3OH(l)+O2(g)--->CO2(g)+2H2O(l) at 298K.Gibb's energy of formation of CH3OH(l)CO2(g) and H2O(l) are -166.2,-394.4 and -237.2 kJ/mol respectively.if standard enthalpy of combustion of methanol is -726kJ/mol the efficiency of fuel cell will be

Answer 1

Answer:

Determine ∆G at 298 K and determine if this reaction is ... CS_2 (l)→C(s)+ 2S(s);∆G=-(67.1) kJ/mol ... combustion of methane, CH4 gas and calculate ∆G° at
