Question

calculate the enthalpy of the combustion of propane for your barbeque

C3H8 + 5O2 -> 3CO2 + 4H2O

propane -105 kJ/mol

CO2 -394 kJ/mol

Water -286 kJ/mol

Ooxygen. 0

Answer 1

Answer #1

Heat of formation of C3H8 , CO2 , H2O, O2 are -104 kj/mol , -393.5 kJ/ mol , -285 KJ/ mol , zero

Heat of combustion = Heat of product - Heat of reactant

= 3* -393.5 + 4 * -285 - [ -104 + 0 ] KJ

= -1180.5 + -1140 + 104 KJ

= -2216.5 KJ
