Explanation:
Hello!
In this case, since the enthalpy change for any process is computed by subtracting the enthalpy of the final state and the enthalpy of the initial state, for the given phase change, we subtract the enthalpy of the liquid (final state) and the enthalpy of the solid (initial state) considering this a melting process:
Which makes sense because this process absorbs energy.

Answer : The equilibrium concentration of at
is,
.
Solution : Given,
Equilibrium constant,
Initial concentration of = 0.260 m
Let, the 'x' mol/L of are formed and at same time 'x' mol/L of
are also formed.
The equilibrium reaction is,
Initially 0.260 m 0 0
At equilibrium (0.260 - x) x x
The expression for equilibrium constant for a given reaction is,
Now put all the given values in this expression, we get
By rearranging the terms, we get the value of 'x'.
Therefore, the equilibrium concentration of at
is,
.
