Consider the reaction 2H2(g) + O2(g) → 2H2O(g). The following bond energies have been determined experimentally:
H-H 436 kJ/mol
O=O 497 kJ/mol
H-O 464 kJ/mol
Suppose we start with 4 mol of hydrogen and end up with 4 mol of H2O.
If the system was at 300 K before the reaction took place, what is the final temperature after the reaction?
