equilibria Flashcards
dynamic equlibrium
rate of forward and backward reactions are equal and concentration of product and reactant remain constant
Le chatliers principle
if the conditions of a system in equilibrium are changed, the position of the equilibrium moves as to reduce that change
brosted lowry strong acid
a proton donor, fully ionised in its aqueous solution
bronsted lowry weak acid
a proton donor, partially ionised in its aqueous solution
he need for a closed system in order to establish
dynamic equilibrium
Reversible reaction:
a reaction in which products can be changed back to reactants by reversing the conditions
by le chatliers principle when temperature is increased
the system opposes the change by favouring the endothermic side
by le chatliers principle when pressure is increased
the system opposes the change by favouring the side with fewer gas moles
by le chatliers principle when reactant concentration is increased
the system opposes the change by favouring the forward reaction
Equilibrium constant expressed in terms of concentration
Equilibrium constant expressed in terms of partial pressure
equi. towards products side
equi. towards reactants side
Kc/Kp changes only with changes in
temperature
The amount of reactants that disappear will always appear in the
the products in the same ratio as present in a balanced equation
An acid is a
proton (H+) donor
