3. Determine the change in enthalpy for the oxidation of ammonia as follows 4 NH (g)5 O2(g) 3 4 NO(g) + 6 H2O( using the foll

Answer 1

Answer #1

reverse and double the first equation

4NH3_(g) -------------> 2N2_(g) + 6H2_(g) $\Delta$ H⁰ = 198.44 kJ

double the second equation

2N2_(g) + 2O2_(g) ---------> 4NO_(g) $\Delta$ H⁰ = 361 KJ

triple the third equation

3H2_(g) + 3O2_(g) ------------> 6H2O_(l) $\Delta$ H⁰ = - 1714.8 KJ

add all the 3 equatio ns

4NH3_(g) -------------> 2N2_(g) + 6H2_(g) $\Delta$ H⁰ = 198.44 kJ

2N2_(g) + 2O2_(g) ---------> 4NO_(g) $\Delta$ H⁰ = 361 KJ

3H2_(g) + 3O2_(g) ------------> 6H2O_(l) $\Delta$ H⁰ = - 1714.8 KJ

------------------------------------------------------------------------------------

4NH3_(g) + 5O2_(g) -------------> 4NO_(g) + 6H2O_(l) $\Delta$ H⁰ = - 1155.36 KJ
