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 0.564 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?
