A) 595.14 J/mol
B) - 5951.4 J/mol
C) 5951.4 J/mol
D) - 595.14 J/mol
E) 21.8 J/mol
Correct Answer: C
Solution :
At equilibrium \[\Delta H=T\cdot \Delta \,S\] \[{{H}_{2}}O(s)\xrightarrow{{}}{{H}_{2}}O(l)\] \[\Delta S={{S}_{{{H}_{2}}O(l)}}-{{S}_{{{H}_{2}}O(s)}}\] \[=(60-38.2)\,J\text{/}mol\text{-}K=21.8\,J\text{/}mol\text{-}K\] \[\Delta H=273\times (21.8)=5951.4\,J\text{/}mol\]You need to login to perform this action.
