Consider the hydrogen–oxygen fuel cell where:

H₂(g) + ½O₂(g) H₂O(l) ΔG° = –237.18 kJ/mol H₂

Which of the following statements is false?

◦ At standard conditions, the maximum work the fuel cell could do on the surroundings is 237.18 kJ/mol.
◦ In the real world, the actual amount of useful work the cell can do is more than 237.18 kJ.
◦ More energy is dissipated as waste heat in the fuel cell than in the reversible pathway.
◦ The reaction is spontaneous and has a positive cell potential.
◦ All of these are true.
