A sample of NH3(g) and O2(g) are placed in a rigid container. When the equilibrium below is established, the partial pressure of H2O(g) is 0.784 atm. What is the partial pressure of NO(g) when the system is at equilibrium?

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
