Lechatelier's principle is

If a system in equilibrium is subjected to a change of concentration, pressure or temperature, the equilibrium shifts in the direction that tends to a null the effect of change.

Applicable to all types of dynamic equilibrium

Given to study the effect of state variables

None of the above

Consider the reaction cquilibrium, 2SO_(2(g)) + O_(2(g)) hArr 2 SO_(3(g)) , Delta H^(@) = - 198KJ . On the basis of Le Chatelier's principle, the condition favourable for the forward reaction is

Increase of temperature as well as pressure

Lowering of temperature and increase of pressure

Any value of temperature and pressure

Le chatelier’s principle is applicable to

Chemical equilibria only
