JEE Mains · Chemistry · STD 11 - 6.1. Equilibrium - 1 (chemical Equilibrium)

\(300 \mathrm{~K}\) पर किसी विशिष्ट अभिक्रिया के लिए, \(\mathrm{K}=10\) है, तब उसी अभिक्रिया के लिए \(\Delta \mathrm{G}^{\circ}\) _______\(\times 10^{-1} \mathrm{~kJ} \mathrm{~mol}^{-1}\) है। (दिया गया है : \(\mathrm{R}=8.314 \mathrm{JK}^{-1} \mathrm{~mol}^{-1}\) है।)

  1. A \(70\)
  2. B \(60\)
  3. C \(80\)
  4. D \(57\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(57\)

Step-by-step Solution

Detailed explanation

\(\Delta \mathrm{G}^{\circ}=-\mathrm{RT}(\mathrm{n} \mathrm{K}\) \(=-8.314 \times 300 \ell \mathrm{n}(10)\) \(=5744.14 \mathrm{~J} / \mathrm{mole}\) \(=57.44 \times 10^{-1} \mathrm{~kJ} / \mathrm{mole}\)
