Use the standard enthalpies of formation for the reactants and products to solve for the ΔHrxn for the following reaction. (The ΔHf of C2H4 is 52.26 kJ/mol, CO2 is -393.509 kJ/mol, and H2O is -241.818 kJ.)
C2H4 (g) + 3O2(g) 2CO2 (g) + 2H2O(g)
ΔHrxn = (-345.64 kJ, -583.07 kJ, or -1,322.91 kJ).
The reaction is: (Endothermic or Exothermic).
