Question
Calculate the equilibrium composition for the reaction when the ratio of H2+1/2 O2<=> H2O
the number of moles of elemental hydrogen to elemental oxygen is unity. The temperature is 2000 K, and the pressure is 1 atm.
-------------------------------
Some tables attached
From table information:
O2:
T = 2000 K
cp = 37.788 kJ / kmol-K
(ho (T) hfo (298)) = 59,169 kJ / kmol
hfo (T) = 0 kJ / kmol
so (T) = 268.656 kJ / kmol-K
gfo(T) = 0 kJ / kmol
