Reversible processes : Reaction in which the products of the reaction can react with one another under same conditions of the reaction to give back the reactants e.g. formation of NH,, HI, SO,, etc. do not go to completion. Irreversible processes : Those in which the products formed do not react to give back the reactants e.g. 2KCI0, ’ 2KCI + 30,. Such processes go to completion e.g. precipitation, the reactions involving evolution of gases, etc. Types of Equilibria (1) Physical equilibrium e.g H,o0) H,0o) (2) Chemical equilibrium e.g.PCI,(g)PCI,(g) +CI,(g) (3) lonicequilibrium e.g. CH,coOH(aq.)cH,co0 (aq)+H(aq)\ PHYSICAL EQUILIBRIUM Process Property becoming constant at equilibrium Solid Liquid Melting point at constant e.g., H,o(s) H,O() pressure Liquid Vapour Vapour pressure (e.g.. P,o) e.g.[H,0() H,O(g) at constant temperature Solute (s) Solute (solution) Concentration of the solute e.g., Sugar(s) Sugar (solution) in the solution at the given temperature Gas(aq) at the given Gas(g) Gas(aq) Gas(g) e.g.. CO,(g) O,(ag) temperature, e.g., [CO,(aq) at the given CO,(g) temperature
