Equilibrium

Postby Helen Shi 1J » Sat Nov 25, 2017 7:59 pm

Why in equilibrium the reaction of reactants turning into products and vice versa is still happening? Why doesn't the reactants completely react with each (so their concentration reaches zero) to form the product?

The reactants don't completely react with each other and form products because the products are also reacting and decomposing into their "reactants." The rate of both reactions are the same, therefore there is no net change.

If we were to alter the temperature, pressure or the concentration of a reagent in a dynamic equilibria reaction, the overall composition would change.

Even though there is no net change at equilibrium, both the forward and reverse reactions are still taking place. In other words the reactants are being formed as fast as they are consumed. Hope that helps!
