According to le chatelier’s principle, what happens when the concentration of reactants is doubled in a chemical reaction that was in equilibrium?

a. the equilibrium shifts to the right to favor the formation of products.
b. the equilibrium shifts to the left to favor the formation of reactants.
c. the equilibrium is unaffected by the increase in concentration.
d. the equilibrium is lost because the concentrations have been disturbed.

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.
