The following gas-phase reaction takes place in a closed, constant volume batch reactor at isothermal (constant temperature) conditions: 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. Assuming ideal gas behavior, what is the reactor pressure (in atm) when the reaction goes to completion?


a. 3.45
b. 3.95
c. 4.09
d. 84.76
