What is Kc? (8)

A constant for a specific reaction at a specific temp to determine how far a reaction will occur KC and Q have the same formula but KC uses concentration of equilibrium for the reactants and products if conc isnt given : mol / vol [products] no of moles ----------------------------- [reactants]no of moles there can be diff values of KC for the same reaction it just depends if youre looking at the forward or reverse reaction ONLY affected by temperature endothermic: increasing temp will shift it to the right so KC value increases exothermic: shifts to the left so the value of KC decreases
