| The Solvay process for making \[N{{a}_{2}}C{{O}_{3}}\] involves the reaction |
| \[2NaHC{{O}_{3}}N{{a}_{2}}C{{O}_{3}}(s)+{{H}_{2}}O(g)+C{{O}_{2}}(g)\] |
| For this reaction \[\Delta {{H}^{o}}=129.2\,kJ/mol,\] \[\Delta {{S}^{o}}=334.2\,J/mol-K\]. From this information, the minimum temperature at which this reaction becomes spontaneous is: |
A) \[460{}^\circ C\]
B) \[1017{}^\circ C\]
C) \[113{}^\circ C\]
D) the reaction is spontaneous at all temperatures
Correct Answer: C
Solution :
[c] At \[{{113}^{o}}C,\,\,\Delta {{G}^{o}}=0\]
