3.32 0.5 mol hydrogen at 300 K, 2 mol nitrogen and oxygen present in the ratio of 3:1, and 0.3 mol of CO are mixed. The nitrogen–oxygen mixture was initially present at 400 K and the initial temperature of CO was 500 K. Fifty per cent of the CO present reacts. If the final temperature o the system raises to 1200 K under adiabatic conditions, and if the standard heat of formation of CO, is two times that of CO, calculate the standard heat of formation of CO. The mean heat capacities in J/mol K are 32.5 for O2, 31.1 for N2, 29.0 for H2, 31.0 for CO, and 49.0 for CO2.

Transcribed Image Text:3.32 0.5 mol hydrogen at 300 K, 2 mol nitrogen and oxygen present in the ratio of 3:1, and 0.3 mol
of CO are mixed. The nitrogen–oxygen mixture was initially present at 400 K and the initial
temperature of CO was 500 K. Fifty per cent of the CO present reacts. If the final temperature o
the system raises to 1200 K under adiabatic conditions, and if the standard heat of formation of
CO, is two times that of CO, calculate the standard heat of formation of CO. The mean heat
capacities in J/mol K are 32.5 for O2, 31.1 for N2, 29.0 for H2, 31.0 for CO, and 49.0 for CO2.
