Considering the reaction stoichiometry, 2.5 moles of O₂ are required to react completely with 1 mole of acetylene C₂H₂.
The balanced reaction is:
2 C₂H₂ + 5 O₂ → 4 CO₂ + 2 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
Then you can apply the following rule of three: if by stoichiometry of the reaction 2 moles of C₂H₂ react with 5 moles of O₂, 1 mole of C₂H₂ reacts with how many moles of O₂?
[tex]amount of moles of O_{2} =\frac{1 mole of C_{2} H_{2} x 5 moles of O_{2} }{2 mole sof C_{2} H_{2}}[/tex]
amount of moles of O₂= 2.5 moles
Finally, 2.5 moles of O₂ are required to react completely with 1 mole of acetylene C₂H₂.
