Solution
The correct option is D 1.8 atm The reaction is, CO2+C⇌2CO
Initial pressure of CO2=0.5atm
Initial pressure of CO=0atm Final pressure ofCO2=(0.5−x)atm
Final pressure of CO=2xatm Total pressure at equilibrium = Partial pressures of CO2andCO Total pressure at equilibrium=(0.5−x)+2x=0.8atm(given) x=0.3 ∴Kp=P2COPCO2=(0.6)20.2=1.8atm
