This reaction takes place in a closed batch reactor at constant temperatue and volume: 2CO + O₂
--> 2CO₂

Initially, the reactor contains 1.438 kmol of CO, 1 kmol of O₂, 1 kmol of CO₂, and 0.5 kmol of N₂
at a total pressure of 5 atm. At time t, the reactor pressure is 4.5 atm. Assuming ideal gas behavior, what is the extent of reaction (in kmol) at time t?

a. -0.11
b. 0.34
c. 0.84
d. 0.39
