equilibrium Flashcards
state le chateliers principle
reactions at equilibrium oppose applied stresses
explain chemical equilibrium
when the rate of forward reaction equals the rate of reverse reaction
what is meant when the reaction is dynamic
the reaction has not stopped
why is the production of ammonia exothermic
less ammonia at high temperature
lower yield
forward reaction is not favoured when temperature increases
Kc equals
products over reactants
explain the effect of the yield on ammonia by compressing by increasing the temperature
more ammonia
produces fewer gaseous moles
what effect does a catalyst have on the haber process
no effect
catalyst does not affect the equillibrium concentrations
catalyst speeds up forward and reverse reactions equally
what happens when the concentration of a reaction is increased
is goes in the direction to remove X
what happens when the concentration of X is decreased
it goes in the direction to replace X
what happens when temperature is increased
goes in endothermic direction
what happens when temperature is decreased
it goes in exothermic reaction
what happens when pressure is decreased
goes to the side with lower number of moles
what happens when pressure is increased
goes to the side with higher number of moles
