WebClick here👆to get an answer to your question ️ In a fuel cell, methanol is used as fuel and oxygen gas is used as an oxidiser. The reaction is: CH3OH(l) + 32O2(g) 12 CO2(g) + 2H2O(l) Calculate standard Gibbs free energy change for the reaction that can be converted into electrical work. If the standard enthalpy of combustion for methanol is - … WebThis right here is in joules. So if we want to write everything in kilojoules, since we already wrote that down, let's write this in kilojoules. So it's 0.242 kilojoules per Kelvin. And so now our Gibbs free energy right here is going to be minus 890 kilojoules minus 290-- so the minus and the minus, you get a plus.
