Unformatted text preview: When Keq increases, we say that the equilibrium is shifted towards the products (i.e. an increase in equilibrium constant implies that the ratio of activities (qualitatively, one could say mole fractions) of products over activities of reactants, increases). Conversely, when Keq decreases, the equilibrium is shifted toward the reactants. Such 194 observation is consistent with LeChatelier’s principle (General Chemistry), which states that when one disturbs a system at equilibrium, the system reacts to minimize the disturbance. For example, let us assume that you run the reaction at some temperature T1 and you reach some equilibrium extent of reaction ξ(T1). Now, you increase the temperature from T1 to T2. What happens? According to LeChatelier’s principle, if the reaction is exothermic (i.e. reaction releases heat), then the reaction will shift in the direction, which tends to minimize the heat released by the system as its temp...
