If 45.98 g of sodium combines with an excess of chlorine gas to form 116.89 g of sodium chloride, what mass of chlorine gas is used in the reaction?
Chapter 50: How are Equilibrium Concentrations Determined 2/20/16 50.1 How are Equilibrium Concentrations Determined How can the Direction of a Reaction be Predicted o Reaction quotient Q, same as the equilibrium constant but concentrations in Q expression not necessarily at equilibrium o Q doesn’t have a fixed value o System at equilibrium Q=K but otherwise Q doesn’t equal K o Only forward reaction can occur o Forward reaction rate has to be greater than reverse reaction rate o Numerator will increase denominator will decrease o Q will become greater than zero but starts as a small number but less than K o Q less than K rate of forward reaction is greater than the
