A) 624.8 K
B) 626.8 K
C) 636.8 K
D) None of these
Correct Answer: B
Solution :
[b] \[Hg(l)\rightleftharpoons H(g),\] \[{{\Delta }_{R}}{{S}^{{}^\circ }}=174.4-77.4=97J/K-mol\] \[\therefore \text{ }\Delta {{G}^{{}^\circ }}=\Delta {{H}^{{}^\circ }}-T\Delta {{S}^{{}^\circ }}=0\] \[T=\frac{\Delta {{H}^{{}^\circ }}}{\Delta {{S}^{{}^\circ }}}\] \[=\frac{60.8\times 1000}{97}=626.8K\]You need to login to perform this action.
