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. For the equilibrium, underset(("yellow"))(Fe^(3+)(aq))+SCN^(-)(aq)hArrunderset(("deep red"))[[Fe(SCN)^(2+)](aq) Select the correct option.

Answer» Addition of `H_(2)C_(2)O_(4)` which FORMS `[Fe(C_(2)O_(4))_(3)]^(3-)` DEEPENS red colour. Addtion of `H_(2)O` has no effect on the colour. Addition of `SCN^(-)` intensifies red colour. Addition of `Hg^(2+)` which forms `[Hg(SCN)_(4)]^(2-)` deepens red colour. Answer :C
