A) \[\because \]
B) \[\Delta {{T}_{f}}\alpha i\]
C) \[\frac{\Delta {{T}_{f}}(KCl)}{\Delta {{T}_{f}}(BaC{{l}_{2}})}=\frac{2}{3}\]
D) \[\Delta {{T}_{f}}(BaC{{l}_{2}})=\frac{3}{2}\times 2={{3}^{o}}C\]
Correct Answer: B
Solution :
\[HI{{O}_{4}},{{H}_{3}}I{{O}_{5}}\] \[{{H}_{5}}I{{O}_{6}}\] Concentration at starting = 10 M Concentration after 20 min (two half-lives) \[4-1,+3,+7\] \[+7,+7,+3\] \[+7,+7,+7\]
