chem module 1a question

[Mallika Singh 1G]

Does K give us information about the relative concentrations of reactant and product?

[Justin Sarquiz 2F]

K is the concentration of the products divided by the concentration of reactants. Therefore, K tells us the relative concentrations between products and reactants. If K >1, then the concentration of products is greater than the concentration of reactants at equilibrium and vice versa.

[Sydney Pell 2E]

K does give the relative concentrations of products to reactants when the equation is at equilibrium. This is because it is calculated using [Products]/[Reactants], thus showing us the ratio of products to reactants. A large K value (greater than 10^3) means more products at equilibrium than reactants. A small K value (less than 10^-3) means more reactants at equilibrium. In this way, K tells us the relationship between products and reactants at equilibrium.
