In designing a chemical plant for manufacturing the plastic polyethylene, you need to know the enthalpy change for the removal of hydrogen from C2H6 to give C2H4. This is a key step on the process C2H6 (g)--> C2H4(g) + H2(g) delta Horxn = ?? From other experiments, you have the following data: 2 C2H6 (g) + 7 O2 (g) --> 4 CO2 (g) + 6 H2O(l) deltaHorxn = -3119.4 kJ C2H4 (g) + 3 O2 (g) --> 2 CO2 (g) + 2 H2O(l) delta Horxn = -1410.9 kJ H2(g) + 1/2 O2(g) ---> H2O(l) delta Horxn =-286 kJ
