Question: Calculate the standard emf at 25°C of the propane fuel cell given that delta G° formation for propane = -23.5 kJ/mol. The overall reaction for the fuel cell is:
C3H8 (g) + 5O2 (g) --> 3CO2 (g) + 4H2O (l)
Given N2 (g) + 3 H2 (g) ? 2 NH3 (g), which scenario will allow you to eventually reach an equilibrium mixture involving these chemicals? Place only H2 into a sealed vessel. Place only N2 into a sealed vessel. Place only NH3 into a sealed vessel.
