I2(aq) + l(aq)⇔I3(aq) This reaction is set-up in aqueous medium. We started with 1 mole of I2 and 0.5 mole of 1 in 1L flask. After equilibrium reached, excess of AgNO3 gave 0.25 mole of yellow precipitate. Equilibrium constant is excess of AgNO3 gave 0.25 mole of yellow precipitate. Equilibrium constant is I2(aq) + l(aq)⇔I3(aq) [...]
