Question

calculate the enthalpy change (H) of the combustion of propane

C3H4

C3H8+5O2=3CO2 + 4H2O

Use the following information

3C + 4H = C3 H8 H= -103.8 kJ/mol

C+O2=CO2 H=-393.5 kJ/mol

H2+1/2O2=H2O h= -241.8 kJ/mol

Expert Solution
Step 1 :- Given Data

3C + 4H2 ---> C3H8  ∆H= -103.8 kJ/mol { Equation 1}

C + O2 ----> CO2  ∆H=-393.5 kJ/mol { Equation 2 }

H2 +1/2 O2 -----> H2O  ∆H= -241.8 kJ/mol { Equation 3 }
