A) \[128\text{ }S\text{ }c{{m}^{2}}mo{{l}^{-1}}\]
B) \[176\,S\text{ }c{{m}^{2}}mo{{l}^{-1}}\]
C) \[278\text{ }S\text{ }c{{m}^{2}}\text{m}o{{l}^{-1}}\]
D) \[302\text{ }S\text{ }c{{m}^{2}}mo{{l}^{-1}}\]
Correct Answer: A
Solution :
By Kohlrausch's law, \[\hat{\ }_{NaBr}^{o}=\hat{\ }_{NaCl}^{o}+\hat{\ }_{KBr}^{o}-\hat{\ }_{KCl}^{o}\] \[=126+152-150\] \[=128\,S\,c{{m}^{2}}mo{{l}^{-1}}\]You need to login to perform this action.
