The equilibrium constant, denoted as $$K_c$$, is a numerical value that represents the ratio of the concentrations of products to the concentrations of reactants at equilibrium for a given chemical reaction. It indicates the extent to which a reaction proceeds and helps to understand how far the reaction favors products or reactants at equilibrium. The value of $$K_c$$ is specific to a particular reaction at a specified temperature and can be influenced by changes in conditions such as concentration, pressure, and temperature.
congrats on reading the definition of kc. now let's actually learn it.
