How many liters of oxygen is required for the complete combustion of 4 liters of acetylene?
| April 4, 2021 | education
The oxidation reaction of acetylene is described by the following chemical reaction equation.
C2H2 + 5/2 O2 = 2CO2 + H2O;
According to the coefficients of this equation, 2.5 oxygen molecules are required to oxidize 1 acetylene molecule. In this case, 2 molecules of carbon dioxide are synthesized.
The molar volume of the gas is standard and fills a volume of 22.4 liters under normal conditions.
Since the molar volume of the gas is standard, a 2.5 times larger amount of oxygen will require 2.5 times its volume.
The required volume of oxygen is 4 x 2.5 = 10 liters.
