Consider the reaction A + B ⇌ C + D, which is in equilibrium at a certain temperature. The reaction is exothermic, and an increase in temperature causes the equilibrium position to shift towards the reactants. However, the reaction is also accompanied by a decrease in volume. Explain how these two opposing factors affect the equilibrium position, and provide a theoretical explanation for the observed behavior.
