   Jun 23, 2023 · Solution. According to Le Chatelier's principle, if pressure is increased, then the equilibrium shifts to the side with the fewer number of moles of gas. This particular reaction shows a total of 4 mol of gas as reactants and 2 mol of gas as products, so the reaction shifts toward the products side.

   4.3 – Solving Equilibrium Problems. We know that at equilibrium, the value of the reaction quotient of any reaction is equal to its equilibrium constant. Thus, we can use the mathematical expression for Q to determine a number of quantities associated with a reaction at equilibrium or approaching equilibrium.

   How to solve equilibrium problems involving changes in concentration?

   • In solving equilibrium problems that involve changes in concentration, it is again very convenient to set up an ICE table. Example 4.3.5 – Calculation of Concentration Changes as a Reaction Goes to Equilibrium Under certain conditions, the equilibrium constant K C for the decomposition of PCl 5 (g) into PCl 3 (g) and Cl 2 (g) is 0.0211.

   How do you stress an equilibrium in a chemical reaction?

   • There are several ways to stress an equilibrium. One way is to add or remove a product or a reactant in a chemical reaction at equilibrium. When additional reactant is added, the equilibrium shifts to reduce this stress: it makes more product. When additional product is added, the equilibrium shifts to reactants to reduce the stress.

   What does it mean if a reaction has reached equilibrium?

   • 1. When a reaction is described as "having reached equilibrium" this means that the forward reaction rate is now equal to the reverse reaction rate. In regards to the amounts or concentrations of the reactants and the products, there is no change due to the forward reaction rate being equal to the reverse reaction rate. 2.

   How can we distinguish between a system that has reached equilibrium?

   • To differentiate between a system that has reached equilibrium and one that is reacting slowly that changes in concentrations are difficult to observe we can use Le Chatelier’s principle to observe any shifts in the reaction upon addition of a constraint (such as concentration, pressure, or temperature).

   How do you predict a reaction at equilibrium?

   • Consider this reaction at equilibrium: N 2 + O 2 (g) ⇆ 2NO (g) Predict whether the reaction will shift left, shift right, or remain unchanged after each disturbance. a) NO is added to the reaction mixture. b) N 2 is added to the reaction mixture. c) NO is removed from the reaction mixture.

   When the concentration of a gaseous or aqueous reactant or product is increased the equilibrium reaction shifts in the direction that decreases the concentration of that substance. If more product is added to a system at equilibrium, the reverse reaction increases in order to use the extra product, shifting equilibrium to the left.
