temperature and pressure affects on chemical equilibrium constant

Postby Jessica Dawood » Sat Mar 16, 2024 12:21 am

hello,
I wanted to ask what is the effect of changing temperature, pressure and volume on equilibrium constant when dealing with product and reactants formation?

Only temperature will have an impact on the equilibrium constant not volume or pressure changes. Temp changes it because you are changing the concentrations depending on if the reaction is endo or exo thermic

Temperature affects K based on if the reaction is endothermic or exothermic. With an exothermic reaction, increasing temperature decreases the equilibrium constant and vice versa. Additionally, pressure and volume don't affect K; Le Chatelier's just states that the position of equilibrium will change, but not the K value itself.

only temperature will ever change the K value, things like concentration, volume, and pressure can shift the position of equilibrium, but the equilibrium constant will stay the same
