Which of the following change at equilibrium will shift reaction in backward direction: `Fe^(3+)(aq)+SCN^(-)(aq)hArrFe(SCN)^(2+)(aq)`A. Addition of waterB. Addition of `KOH(aq)[Fe(OH)_(3)` is insoluble in water]C. Addition of `NaNO_(3)(s)`D. A and B both

Answer» `Fe^(3+)(aq)+SCN^(-)(aq)hArrFe(SCN)^(2+)(aq)`
(A) For given Q `alpha` V `rArr` on addition of water `QgtK` reaction move backward
(B) `Fe^(+3)+3OH^(-)hArrFe(OH)_(3)(s)` reaction moves backward
