Consider the following reaction at equilibrium. what effect will adding 2.3 mole of rn to the reaction mixture have on the system? 2 h2s(g) + 3 o2(g) ⇌ 2 h2o(g) + 2 so2(g) no effect will be observed. the equilibrium constant will increase. the equilibrium constant will decrease. the reaction will shift to the right in the direction of products. the reaction will shift to the left in the direction of reactants.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

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.
