Question 1
The free energy of formation of nitric oxide, NO, at 1000 K (roughly the temperature in an automobile engine during ignition) is about 78 kJ/mol. Calculate the equilibrium constant K
p for the reaction N
2(g) + O
2(g)
2NO(g) at this temperature.
Question 2
The heat of vaporization of water is 2.27 kJ/g. What is ΔS
vap per mole at the normal boiling point?
