How much heat is absorbed/released when 35.00 g of NH3(g) reacts in the presence of excess O2(g) to produce NO(g) and H2O(1) according to the following chemical equation?
4 NH₃(g) + 5 O₂(g) --> 4 NO(g) + 6 H₂O(l) ΔH⁰ = 1168 kJ
a. 600.1 kJ of heat are released.
b. 600.1 kJ of heat are absorbed.
c. 2400 kJ of heat are released.
d. 2400 kJ of heat are absorbed.
