  2. B \(42\)
  3. C \(36\)
  4. D \(44\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(36\)

Step-by-step Solution

Detailed explanation

\(ClCH _{2} COOH \rightleftharpoons ClCH _{2} COO ^{\ominus}+ H ^{+}\) \(i =1+(2-1) \alpha\) \(i =1+\alpha\) \(\Delta T _{ f }= ik _{ f } m\) \(0.5=(1+\alpha)(1.86)\left(\frac{\left(\frac{9.45}{94.5}\right)}{\left(\frac{500}{1000}\right)}\right)\)…
