There are several factors that can affect the equilibrium of a chemical reaction, including temperature, pressure, concentration of reactants and products, and the presence of catalysts.
Two factors that I have studied are temperature and concentration.
Temperature: Changes in temperature can affect the equilibrium position of a reaction. In an exothermic reaction, increasing the temperature will shift the equilibrium towards the left, favoring the reactants. In an endothermic reaction, increasing the temperature will shift the equilibrium towards the right, favoring the products. This is because increasing the temperature provides more energy for the reaction to occur in the direction that absorbs or releases heat.
Concentration: Changes in the concentration of reactants or products can also affect the equilibrium position of a reaction. If the concentration of reactants is increased, the equilibrium will shift towards the products to consume the excess reactants. Conversely, if the concentration of products is increased, the equilibrium will shift towards the reactants to consume the excess products. This is known as Le Chatelier's principle, which states that a system at equilibrium will respond to a stress by shifting in the direction that relieves the stress.

Factors that Affect Equilibrium
- Concentration: Increasing the concentration of reactants shifts the equilibrium towards products, while decreasing the concentration of products shifts the equilibrium towards reactants.
- Temperature: Raising the temperature shifts the equilibrium towards the endothermic reaction, while lowering the temperature shifts the equilibrium towards the exothermic reaction.
- Pressure: Increasing the pressure shifts the equilibrium towards the side with fewer moles of gas, while decreasing the pressure shifts the equilibrium towards the side with more moles of gas.
- Addition or removal of products or reactants: Adding more products or reactants shifts the equilibrium towards the side that consumes them, while removing products or reactants shifts the equilibrium towards the side that produces them.
- Addition of a catalyst: A catalyst does not shift the equilibrium position; it only speeds up the rate of approach to equilibrium.
Two Factors Studied in Detail
1. Concentration:
- When the concentration of reactants is increased, the forward reaction is favored, and the equilibrium shifts to the right (towards products).
- When the concentration of products is increased, the reverse reaction is favored, and the equilibrium shifts to the left (towards reactants).
- For example, in the reaction A + B ⇌ C + D, increasing the concentration of A or B would shift the equilibrium to the right, producing more C and D. Conversely, increasing the concentration of C or D would shift the equilibrium to the left, consuming more C and D.
2. Temperature:
- For exothermic reactions (δH < 0), increasing the temperature shifts the equilibrium to the left (towards reactants).
- For endothermic reactions (δH > 0), increasing the temperature shifts the equilibrium to the right (towards products).
- This is because temperature changes the relative stability of the reactants and products. At higher temperatures, the more endothermic reaction (which requires more energy) is favored, while at lower temperatures, the more exothermic reaction (which releases more energy) is favored.
- For example, in the reaction N2 + 3H2 ⇌ 2NH3 (δH = -92 kJ/mol), increasing the temperature shifts the equilibrium to the left (consuming more N2 and H2). Conversely, decreasing the temperature shifts the equilibrium to the right (producing more NH3).
- Concentration: Increasing the concentration of reactants shifts the equilibrium towards products, while decreasing the concentration of products shifts the equilibrium towards reactants.
- Temperature: Raising the temperature shifts the equilibrium towards the endothermic reaction, while lowering the temperature shifts the equilibrium towards the exothermic reaction.
- Pressure: Increasing the pressure shifts the equilibrium towards the side with fewer moles of gas, while decreasing the pressure shifts the equilibrium towards the side with more moles of gas.
