The combustion of carbon monoxide is carried out in a closed, rigid and insulated vessel. 1 mol of CO, 0.5 mol of O2 and 2 mol of N2 are taken initially at 1 bar and 298 K, and the combustion is carried out to completion.
The standard molar internal energy change of reaction (ΔuR°) for the combustion of carbon monoxide at 298 K=-282 kJ mol-1. At constant pressure, the molar heat capacities of N2 and CO2 are 33.314 J mol-1K-1 and 58.314 J mol-1K-1, respectively. Assume the heat capacities to be independent of temperature, and the gases are ideal. Take R=8.314 J mol-1K-1.
The final pressure in the vessel at the completion of the reaction is _______ bar (round off to 1 decimal place).
