rates of reaction - concentration, temperature and pressure on rtes of reaction Flashcards
(10 cards)
what happens when a system is at equillibrium and a change is made to the conditions
the system tries to counteract this change
what principle is this known as
La chateliers Principe
what happens if we change the concentration of the reactants and the products
then the system is no longer at equilibrium
when we increase, the reaction will
decrease
what is meant hen it says the forward reaction is exothermic
when the forward reaction takes place, energy is released and the temperature of the system increases
in a reversible reaction what does it mean if the forward reaction is exothermic
then the backwards reaction is endothermic
what does pressure effect
reactions involving gases
what does the pressure of gas depend on
the number of molecules
what happens if we increase the pressure of a reaction at equilibrium
the position of equilibrium shifts to the side with the salter amount of molecules
what does changing the pressure do to a reaction that has the same number of molecules for its products and reactants
no effect
