Which of the following change at equilibrium will shift reaction in backward direction: Fe^(3+)(aq)+SCN^(-)(aq)hArrFe(SCN)^(2+)(aq)

Answer»

Addition of water
Addition of `KOH(aq)[Fe(OH)_(3)` is insoluble in water]
Addition of `NaNO_(3)(s)`
A and B both

Solution :`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
