Very Large K

Postby Lindsey Chheng 1E » Mon Jan 06, 2020 9:28 pm

what does it mean when K is a very large value and not just simply >1 but more like >>>>>1?

I believe that having a very large K (like larger than 10^3) indicates that the equilibrium strongly favors the products, and that there's a higher amount of products present at some time.

A very large K value means the reaction at equilibrium will heavily lean towards the products. The equilibrium constant is basically concentration of products over concentration of reactants, so for K to be a large value, the numerator (product) should be big while denominator (reactant) should be small.

K stands for the equilibrium constant and represents the fixed ratio between products and reactants under specific conditions. If K is large, there is a higher percentage of products in the equilibrium solution in comparison to reactants. This emphasizes that the forward reaction is therefore stronger (more likely to occur) than the reverse reaction.

In addition to what everyone else has already mentioned, it means that the products are much more stable than the reactants in the chemical equation provided.

Seeing as the formula for K is K = [P]/[R], the larger the concentration of products and the smaller the concentration of reactants there are, the larger K will be.

the higher the K, the more the products are favored. If the K is extremely large, theoretically there would not be a backward reaction because only the forward reaction is favored.

Conversely, a very very small K means the left side of the reaction is favored.

At what point should we put the single arrow and not the double arrow?

Would a solution that is just a solute in water have a K value?

Since K is just Product/ Reaction. A large K means a large amount of Product, so the rxn would mainly producing product or shifting to the right

A large K would mean the product concentration in the equation is much greater than the reactant. Therefore, the reaction at equilibrium favors the products.

This means that at equilibrium more products are present than reactants. In this case, a lot more
