Chemistry · EQUILIBRIUM
हिन्दीUsing the ideal gas relationship \( p = cRT \) where \( c = n/V \), what is the partial pressure of \( \text{NO}(\text{g}) \) at equilibrium in a vessel at \( 800\text{ K} \) where its equilibrium concentration is \( 2.8 \times 10^{-3}\text{ mol L}^{-1} \)? (Take \( R = 0.0831\text{ bar L mol}^{-1}\text{K}^{-1} \))
Correct answer · Option A
0.186 bar
Explanation
\( p = cRT = (2.8 \times 10^{-3}\text{ mol L}^{-1}) \times (0.0831\text{ bar L mol}^{-1}\text{K}^{-1}) \times (800\text{ K}) = 2.8 \times 10^{-3} \times 66.48 \approx 0.186\text{ bar} \).
