298 K पर अभिक्रिया \(2 \mathrm{~A}+\mathrm{B} \rightarrow \mathrm{C}\) के लिए, \(\Delta \mathrm{H}\) \(=400 \mathrm{~kJ} \mathrm{~mol}^{-1}\) और \(\Delta \mathrm{S}=0.2 \mathrm{~kJ} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}\) है। अभिक्रिया _______ \(\mathrm{K}\) के ऊपर स्वतः प्रवर्तित होगी।

  1. A \(1000\)
  2. B \(2000\)
  3. C \(100\)
  4. D \(200\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(2000\)

Step-by-step Solution

Detailed explanation

\(\Delta \mathrm{G}=0\) \(\mathrm{~T}=\frac{\Delta \mathrm{H}}{\Delta \mathrm{S}}=\frac{400}{0.2}=2000 \mathrm{~K}\)
