What will be the melting point of KCl if enthalpy change for the reaction is `"7.25 J mol"^(-1)` and entropy change is `"0.007 J K"^(-1)"mol"^(-1)`?

Text Solution

Verified by Experts

The entropy of fusion is given by
`Delta_("fus")S = (Delta_("fus")H)/(T_m)`
Given that `Delta_(fus) H = 7.25 kJ mol^(-1), Delta_(fus) S = 0.007 kJ mol^(-1) K^(-1), T_m = ?`. Substituting the values, we have
`0.007 = 7.25/T_m`
`or T_m = 7.25/(0.007) = 1035.7 K`
Hence, the melting point of KCl is 1035.7 K.
