Question
Determine the equilibrium constant of the reaction at 298 K.
![]()
From the obtained value of the equilibrium constant, predict whether Sn2+ ions can reduce Fe3+ to Fe2+ quantitatively or not.
![]()
Solution
The cell is
and
and n = 2
∴
As K is very high, the reaction is favoured in the forward direction, so, Sn2+ can easily reduce Fe3+ ion to Fe2+ ion.
