If the added substance is a reactant, the equilibrium shifts toward products. If it is a product, it moves towards reactants.
Adding more of a compound to a system at equilibrium will shift the equilibrium towards the products if the added compound is a reactant, and towards the reactants if the added compound is a product. This is to counteract the change and re-establish equilibrium.
If the added substance is a reactant, the equilibrium shifts toward products. If it is a product, it moves towards reactants.

According to Le Chatelier's principle, if more of one compound in a reaction at equilibrium is added, the system will shift in the direction that counteracts the change. This typically means it will favor the reaction that consumes the added substance, either producing more products or reducing the concentration of the added compound. As a result, the system will reach a new equilibrium state with adjusted concentrations of the reactants and products.

The reaction would shift to balance the change
If heat is added to a system at equilibrium, the position of the equilibrium will shift according to Le Chatelier's principle. For an exothermic reaction, adding heat will shift the equilibrium to the left, favoring the reactants, while for an endothermic reaction, it will shift to the right, favoring the products. This adjustment occurs as the system seeks to counteract the change in temperature.
If the temperature of a reaction mixture at equilibrium is decreased, the system will respond by favoring the exothermic direction of the reaction to produce heat. According to Le Chatelier's principle, this shift will result in an increase in the concentration of products if the forward reaction is exothermic, or an increase in reactants if the reverse reaction is exothermic. The overall effect will be a change in the equilibrium position to counteract the decrease in temperature.
According to Le Chatelier's principle, if heat is added to a system at equilibrium, the system will respond by shifting the equilibrium position in a direction that absorbs the added heat. This typically means favoring the endothermic reaction, where heat is a reactant. As a result, the concentrations of the products and reactants will change until a new equilibrium is established. This principle helps predict how changes in temperature affect the chemical equilibrium of a reaction.
The concentrations of reactants and products are modified.
