Chemistry: C4 - dynamic equilibrium

what is a dynamic equilibrium

when the forward and reverse reactions happen at the same time, at the same rate with no observational change

what is the haber process

a process used to make ammonia by reacting nitrogen with hydrogen

what happens as the reactants A and B react

• their concentrations fall

• the forward reaction will slow down

what happens when the products C and D are made

• their concentrations increase

• the backwards reaction speeds up

will the forwards and backwards reactions ever happen at the same rate

yes an this is called equilibrium

are the reactions still happening at the equilibrium

yes but their is no overall effect, this is called dynamic equilibrium because they happen at the same rate with no change

how is the pnly way to reach equilibrium

is the reversable reaction takes place in a closed system

what does a closed system mean

that the reactants and/or products can’t get out

are the amounts of reactants and products at equilibrium equal

no they aren’t

• sometimes the equilibrium will lie to the right which means there are more products

what are three things that can change the equilibrium

• temperature

• pressure if it involves gases

• concentrations of reactants and/or products
