Study the figure given below and mark the correct expression.
\[\begin{array}{l} X Y_{(g)} \xrightarrow{\Delta H_{\mathrm{golm}}^{\circ}} X_{(\mathrm{aq})}^{+}+Y_{(\mathrm{aq})}^{-} \\ \frac{\Delta H_{\text {lattice }}^{\circ}}{X_{(\mathrm{g})}^{+}+Y_{(g)}} \end{array}\]
The enthalpy of solution of XY(s), ΔH° soln. in water can be determined by
\[\begin{array}{l} X Y_{(g)} \xrightarrow{\Delta H_{\mathrm{golm}}^{\circ}} X_{(\mathrm{aq})}^{+}+Y_{(\mathrm{aq})}^{-} \\ \frac{\Delta H_{\text {lattice }}^{\circ}}{X_{(\mathrm{g})}^{+}+Y_{(g)}} \end{array}\]
The enthalpy of solution of XY(s), ΔH° soln. in water can be determined by
- DH° lattice = DH° hyd + DH° soln.
- DH° hyd = DH° lattice + DH° soln.
- DH° soln. = DH° lattice + DH° hyd
- DH° soln. = DH° lattice × DH° hyd
Answer
(C) D H ° soln. = D H ° lattice + D H ° hyd
