Question

A vessel at 1000 K contains carbon dioxide with a pressure of 0.5 atm. Some of the carbon dioxide is converted to carbon monoxide on addition of graphite.
CO2+C2CO
Calculate the value of Kp if total pressure at equilibrium is 0.8 atm. 


A
2.5 atm
loader
B
1.1 atm 
loader
C
0.5 atm
loader
D
1.8 atm
loader

Solution

The correct option is D 1.8 atm
The reaction is, CO2+C2CO

Initial pressure of CO2=0.5 atm
Initial pressure of CO=0 atm
Final pressure of CO2=(0.5x) atm  
Final pressure of CO=2x atm
Total pressure at equilibrium = Partial pressures of CO2 and CO
Total pressure at equilibrium=(0.5x)+2x=0.8 atm (given) 
x=0.3
Kp=P2COPCO2=(0.6)20.2=1.8 atm
