The Total solution for NCERT class 6-12
At 1127 K and 1 atm pressure, a gaseousmixture of CO and CO2 in equilibrium with solid carbon has90.55% CO by mass
Calculate Kc for this reaction atthe above temperature.
Letthe total mass of the gaseous mixture be 100 g.
Massof CO = 90.55 g
And, mass of CO2 = (100 – 90.55) =9.45 g
Partialpressure of CO,
Partial pressure of CO2,
Forthe given reaction,
Δn = 2 – 1 = 1
Weknow that,
