Question

If 2.0 liters of oxygen gas react with excess carbon monoxide at 273 K and 1.00 atm, how many liters of carbon dioxide can be produced under the same conditions? 2 CO (g) + O2 (g) yields 2 CO2 (g)

Answer 1

2.0 liters of carbon dioxide will be produced under the same conditions.

Step-by-step explanation:

To determine the volume of carbon dioxide (CO2) produced when 2.0 liters of oxygen gas react with excess carbon monoxide (CO), we need to use the stoichiometry of the balanced chemical equation:

2 CO (g) + O2 (g) -> 2 CO2 (g)

Since the stoichiometric ratio is 2:2, the same volume of carbon dioxide will be produced. Therefore, 2.0 liters of carbon dioxide will be produced under the same conditions.

Answer 2

The given condition is STP, under this condition, gas has a rule of 22.4 L per mole. And the given equation is already balanced. The ratio of mole number is the same as the ratio of the volume and is also the same as the ratio of coefficients. So the answer is 4.0 liters.
