Whatis achemicalequilibrium? What areitscharacteristics ?

Answer»

SOLUTION :ChemicalEquilibrium:Itis stateof a reversiblechemicalreactionin whichno changein theamountof reactantsandproductstakesplace . Atequilibrium,
Rateof FORWARDREACTION= Rateofbackwardreaction
Characteristicsof equilibrium:
(i) IN chemical equilibrium, the ratesof forwardand backwardreactionsare EQUAL .
(ii )the observablepropertiessuchas pressure , concentration, colorr, density, viscosityetc.,
of thesystem reamainunchangedwithtime .
(III )Thechemicalequilibriumis a dynamicequilibrium, becauseboththe forwardandbackwardreactionscontinueto occureventhough it appearsstaticexternally.
(iv )In physicalequilibrium, thevolumeof ALLTHE phasesremainconstant
