Webb21 apr. 2024 · The reaction it stays for is thus: C2H6 + 3.5 O2 ==> 2CO2 + 3 H2O The correct answer is thus twice higher. It says that the combustion of C2H6 liberates 1.5x10^3 kJ/mole of C2H6. Using your equation we have 14 mols O2 x 1 mol C2H6 / 3.5 mol O2 = 4 mols C2H6 combusted. 4 mol C2H6 x 1.5x10^3 kJ/mol = 6x10^3 kJ.

In chemistry and thermodynamics, the standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements in their reference state, with all substances in their standard states. The standard pressure value p = 10 Pa (= 100 kPa = 1 bar) is recommended by IUPAC, although prior to 1982 the value 1.00 atm (101.325 kPa) was used. There is no standard temperature. Its symbo… WebbThe standard enthalpy of combustion of ethene gas, C2H4, is -1411.1 kJ/mol at 298 K.
