Chemical Equilibria Flashcards
What are equilibrium reactions?
are reversible reactions in which forward and backward reactions take place at the same time
What are some characteristics of equilibrium state?
it is dynamic, equilibrium occurs only in a closed system, at equilibrium the rate of the forward and backward reactions are equal
What is equilibrium?
is reached when the rate of forward and backward reactions are the same
What is the partial pressure?
is the pressure exerted by the molecules of a particular gas in a mixture of gases
symbol- p
What is Le Chatelier’s principle?
if one or more factors that affect an equilibrium are changed, the position of equilibrium shifts in the direction which opposes the change
What is a solubility product?
is an expression showing the equilibrium concentration of ions in a saturated solution of a sparingly soluble salt
Ksp
What is the common ion effect?
is the reduction in the solubility of a dissolved salt caused by adding a solution of a compound
What is the Kp etc values?
