Carbon monoxide reacts with oxygen to form carbon dioxide.

2 CO (g) + O2 (g) → 2C02 (8)

In a 1.00 L flask, 3.40 atm of CO reacts with 2.60 atm of O2. Assuming that the temperature remains constant, what is the final pressure in the flask?

4.30 atm

2.60 atm

3.40 atm

6.00 atm

    The total pressure in the flask = 4.30 atm

    Explanation:

    Step 1: Data given

    Volume of the flask = 1.00 L

    Pressure of CO = 3.40 atm

    Pressure of O2 = 2.60 atm

    Step 2: The balanced equation

    2 CO (g) + O2 (g) → 2C02

    Step 3: Calculate the final pressure

    3.40 atm of CO reacts with 1.70 atm of O2

    There will remain 2.60 - 1.70 = 0.90 atm O2

    There will be produced 3.40 atm of CO2

    The total pressure in the flask = 0.90 atm + 3.40 atm = 4.30 atm
