Concentration affecting equilibrium

Postby Clarice Chui 2C » Sun Jan 12, 2020 9:44 pm

How does changing concentration of the products affect an equilibrium reaction?

I think that decreasing the concentration of products will decrease the reaction quotient while increasing the concentration pf products will increase the reaction quotient

Changing the concentrations does not change the K value. However, in the short term it will change the value of Q. Adding more products will make the value of Q larger and if Q>K then the system will favor the formation of reactants and vice versa.

Can someone clarify how taking out some of the product can increase the amount of product made without considering temperature or additional input?

To clarify, when you remove some of the product, the concentration of the product will decrease, while the amount of reactants will stay the same. Thus, as you remove more product, Q will be less than K. When Q<K, the reaction proceeds forward and more product will be made.

Keeping in mind that the equilibrium constant is the ratio between concentration of products and concentration of reactants, if the concentration of products is increased, then the reaction's Q>K, and if the concentration of products is decreased then Q<K and Chatelier's principle will continue to try to bring it back into equilibrium by minimizing what has happened.
