Answer to Question #203757 in General Chemistry for demy

Question #203757

2N2 (g) +5O2 (g) +2H2 O(l)  4HNO3 (aq), ΔH1 = -255 kJ

Η2 (g) + 1/2O2 (g) H2O( l), ΔH2 = - 256 kJ

S(s) + H2 (g) +2O2 (g)  H2SO4 (aq), ΔH3 = - 814 kJ

N2 (g) + 2O2 (g)  2NO2 (g), ΔH4 = +66 kJ

Να υπολογίσετε την πρότυπη ενθαλπία της αντίδρασης:

6HNO (aq) + S(s)  H2 SO4 (aq) 6NO (g) 2H2 O (l )
