Chemistry in Society: Equilibria Flashcards
A reversible reaction is said to have what?
Attained a state of dynamic equilibrium when the rate of the forward reaction is equal to the rate of the reverse reaction
What can affect a system at equilibrium?
Concentration of reactants or products, temperature and pressure
A catalyst does what to equilibrium?
It does not affect the position of equilibrium but it does, however, allow the reaction to reach equilibrium more quickly
What happens in the addition of reactant or removal of product?
Equilibrium shifts to the right
What happens in addition of product or removal of reactant?
Equilibrium shifts to the left
What happens when temperature is increased?
Equilibrium shifts in direction of endothermic reaction
What happens when temperature decreases?
Equilibrium shifts in direction of exothermic reaction
What happens when pressure is increased?
Equilibrium shifts in direction which reduces the number of molecules in gas phase
What happens when pressure is decreased?
Equilibrium shifts in direction which increases the number of molecules in gas phase
