equilibibrium Flashcards
what is a closed system
no external interactions ( no chnage in pressure temp or conc). no substances leave.
what happens at dynamic equilibrium
the rate of the forwards and backwards reaction are equal. at equilibrium concentration of products and reactants are constant.
what is le chatelliers principle
if the conditions of a reaction at equilibrium are changed, then the position of the equilibrium moves to oppose that change within a closed system
what effect do catalysts have on the position on equilibrium
it speeds up the forwards and backward reaction equally. NO POSITION CHANGE. but it does reach equilibrium faster
where does the position of equil move when pressure is change d
to the side of lesser moles
where does the position of equil move when temp is changed
to counteract the endo or exo change
