Propane Gas Barbeque
Enthalpy and Thermochemical Stoichiometry?
If a roast of pork to absorb 1500 kJ to fully cook, and when only 10% of the heat produced by the barbecue is actually absorbed by the roast, what mass of CO_2 emitted to the atmosphere during the interrogation of pork? The C_3H_8 fuel propane used in barbecue gas is burned under the following thermochemical equation: C_3H_8 (g) + 5O_2 (g) ---> 3CO_2 (g) + 4H_2O (g) ΔH =- 2217kJ How can I fix this?
The total heat required (at 10% efficiency) is 1.500 * 100/10 = 15000kJ One mole of C3H8 produced 2217kJ, so as to produce 15000kJ need 15000/2217 = 6.77 moles moles C3H8 CO2 = 6.77 * 3 (1:3 ratio in the equation) = 20.31 So mass of CO2 = 20.31 * 44 = 893g (Mr. CO2 = 44)
