For the reaction, 2NO(g)+O2(g)→2NO2(g) the value of ΔH is −113.1 – InterviewSolution

1.	For the reaction, 2NO(g)+O2(g)→2NO2(g) the value of ΔH is −113.1 kJ. If 6.0 moles of NO reacts with 3.0 moles of O2 at 1.0 atm and 300 K to form NO2. Calculate the work done against a pressure of 1.0 atm. (Take R=112 L atm mol−1K−1)
Answer» For the reaction, $2 N O (g) + O_{2} (g) \to 2 N O_{2} (g)$ the value of $Δ H$ is $- 113.1 kJ$ . If $6.0 moles$ of $N O$ reacts with $3.0 moles$ of $O_{2}$ at $1.0 atm$ and $300 K$ to form $N O_{2}$ . Calculate the work done against a pressure of $1.0 atm$ . (Take $R = \frac{1}{12} {L atm mol}^{- 1} K^{- 1}$ )
