The state of equilibrium is in a dynamic balance between forward and backward reaction. This balance can be disturbed by changing concentration, temperature or pressure. If done so a cartain net change occurs in the system. The direction of change can be predicted with the help of Le Chatelier principle. It states that when a system in equilibrium is disturbed by a change in concentration of temperature, a 'net' change occurs in it in a direction that tends to decrease the disturbing factor. Consider the following exothermic heterogenous equilibrium, M_(2)O(s)+2HNO_(3)(aq)hArr2MNO_(3)(aq)+H_(2)O(l) withK_(C)=3 at 300K. Select the incorrect option.

Answer» Addition of `H_(2)O(l)` to above EQUILIBRIUM has no EFFECT on equilibrium COMPOSITION `(%)` of `HNO_(3)` and `MNO_(3)`. On dilution, concentration of both `HNO_(3)` and `MNO_(3)` decreases. At 310 K, `K_(C)lt3`. `K_(C)` is dependent on equilibrium concentration of `HNO_(3)`. Answer :D
