define chemical equilibrium
state of dynamic balance where the rate of the forward reaction equals the rate of the reverse rection
what is Le Chateliers principle
if a stress is applied to a system at equilibrium, the system readjusts to relieve the stress applied
what does Le Chateliers principle predict?
in all-gaseous reaction an increase in pressure will favour the reaction which takes place with reduction in volume i.e. towards the side with the smaller number of molecules
