Q favoring products or reactants

[305910012]

what does it mean when the value of Q is large? Does it mean the reaction favors reactants in the equilibrium reaction?

[Amber Shanks 2K]

Yes, when Q is large this means that it is greater than the K value, the equilibrium constant. This means that there is a greater concentration of products and the equilibrium has to move over to the reactants to balance out.

Hi,
A high Q value indicates a higher concentration of products compared to reactants. As a result, the reaction favors the products at that moment, rather than at equilibrium. So yes you are right!

[Bryan Lee 2L]

Yes since Q is products/reactants, a high Q value would mean there are currently a lot of products. If Q is larger than K, than the reaction would favor the reactant side in order to bring it back to K.

When Q is large, it means that the concentrations (or partial pressures) of the products are high compared to the concentrations (or partial pressures) of the reactants. The reaction favored the formation of products
