i2 + i-i3- this reaction is setup in an aqueous medium. we start with 1mol of i2 and 0.5mol of i- in 1litre flask. after equilibrium is reached, excess of agno3 gave 0.25 mol of yellow precipitate. whats the equilibrium constant?

4/3. This is because conc. Of i- ion at equilibrium is 0.25mol and that of i2 is 0.75 and of i3- is 0.25

Can you please provide a more solution to this question .. please ...... Please provide the relevant equations and other necessities ...
