QAIPMT-2008-Ch-2229: NEET 2008 Chemistry - Class 11 AIPMT-2008-Ch-2229 Solution: If the concentration of \(OH^-\) ions in the reaction…
If the concentration of ions in the reaction is decreased by 1/4 times, then equilibrium concentration of will increase by
Multiple Choice Options
- A 64 times
- B 4 times
- C 8 times
- D 16 times
Step-by-Step Verified Solution
Fe(OH) 3(s) _ Fe 3+ (aq) + 3OH _ (aq)
Equilibrium constant, K c = [ F e 3 + ] [ O H _ ] 3 [ F e ( O H ) 3 ]
We know, equilibrium constant remains same at constant
temperature.
Now, let the increase in concentration of Fe 3+ be x
times.
_ K c = [ x _ F e 3 + ] [ 1 4 _ O H _ ] 3 [ F e ( O H ) 3 ]
= x 64 [ F e 3 + ] [ O H _ ] 3 [ F e ( O H ) 3 ]
_ K c = x 64 K c
_ x 64 = 1
_ x = 64
