Based in the equation of the reaction, oxygen gas, O2 is the limiting reactant and 2 moles of CO remain unreacted

What is the equation of reaction between CO and O2?

The reaction of carbon(ii) oxide, CO and oxygen, O2 is a redox reaction which produces carbon (iv) oxide, CO2.

The equation of the reaction. is given below:

  • 2 CO + O2 ----> 2 CO2

From the equation of the reaction, 2 moles of CO are required to react with 1 mole of O2 to produce 2 moles of CO2

The moles of the reacting substances is calculated using the formula:

  • moles = mass/molar mass

Molar mass of CO = 28 g

Moles of CO = 112/28 = 4 moles

Molar mass of 02 = 32 g

Moles of O2 = 32/32 = 1 mole

Therefore, oxygen gas, O2 is the limiting reactant and 2 moles of CO remain unreacted.
