Fuel cells use nitrogen to dilute a mixture of hydrogen with water and oxygen, which is formed from the decomposition of water, which is used to generate electricity and heat. What is the enthalpy of mixing (ΔHmixed, in kJ) that results from diluting an ideal mixture of 0.5 mol of hydrogen, 0.1 mol of oxygen and 3 mol of water with 8 mol of nitrogen to feed a fuel cell? Also, find ΔS mixed. Temperature is 850K.
