Air Acetylene
what is H0f of C2H2 (g)?
Acetylene burns in air using the following equation. C2H2 (g) + 2.5 O2 (g) 2 CO2 (g) + H2O (g) = -1255.8 KJ H0rxn Since H0f CO2 (g) = -393.5 kJ / mol and H0f H2O (g) = -241.8 kJ / mol, which is of H0f C2H2 (g)?
C2H2 (g) + 2.5 O2 (g) -> 2 CO2 (g) + H2O (g) dH rxn = products – reactants (DHF O2 = zero) – 1255.8 kJ = [(2) (-393.5) and 1 (-241.8)] – C2H2 (g) reagents (Cases of dengue hemorrhagic O2 = zero) – 1255.8 kJ = [-1028 , 8] – C2H2 (G) C2H2 (g) = 1255.8 -1028.8 kJ ANSWER = 227.0 kJ / mol
