A) 30%
B) 10%
C) 5.2%
D) 2.7%
Correct Answer: D
Solution :
\[\Delta {{T}_{f}}={{K}_{f}}\times m\times i\] \[i=\frac{\Delta T}{{{K}_{f}}\times m}=\frac{1.91}{1.86\times 1}=1.02\] For\[\underset{(1-\alpha )}{\mathop{HI}}\,\underset{\alpha }{\mathop{{{H}^{+}}}}\,+\underset{\alpha }{\mathop{{{I}^{-}}}}\,\] \[1-\alpha +\alpha =i=1.027\] \[1+\alpha =1.02\] \[\alpha =0.02\]or2.7%You need to login to perform this action.
