\(यदि (K_b=0.60\),K kg mol\(^{-1}), (m=0.20\),mol kg\(^{-1}) और देखा गया उबालांक उन्नयन (0.18\),K) है तो (i) क्या होगा?
\(If (K_b=0.60\),K kg mol\(^{-1}), (m=0.20\),mol kg\(^{-1}), and observed boiling point elevation is (0.18\),K), what will be (i)?
Correct answer and explanation
C. (1.50)
Concept
\(सामान्य उन्नयन (K_bm=0.60\times0.20=0.12\),K) होगा। \(/ Normal elevation is (K_bm=0.60\times0.20=0.12\),K).
Why this answer is correct
\(i=\frac{0.18}{0.12}=1.50\)। / \(i=\frac{0.18}{0.12}=1.50\).
Exam Tip
देखा गया मान सामान्य से अधिक हो तो वियोजन की संभावना होती है। / If observed value is higher than normal, dissociation is likely.
