Sulfur dioxide diffuses faster than CO2 because sulfur dioxide has a lighter molecular weight and a smaller size compared to CO2. This allows sulfur dioxide molecules to move more quickly and easily through a medium, resulting in faster diffusion rates.
Carbon dioxide (CO2).
The molar mass of carbon dioxide (CO2) is 44.01 g/mol, while the molar mass of sulfur dioxide (SO2) is 64.06 g/mol. Since both gases occupy the same volume and have different molar masses, the sulfur dioxide molecules are heavier than the carbon dioxide molecules, resulting in the 22.4 liters of SO2 being heavier than the 22.4 liters of CO2.
The balanced chemical equation for the reaction is: CS2 + 3O2 -> CO2 + 2SO2. This shows that 1 molecule of carbon disulfide reacts with 3 molecules of oxygen gas to produce 1 molecule of carbon dioxide and 2 molecules of sulfur dioxide.
Carbon dioxide is a colorless gas naturally found in the atmosphere and is produced by burning fossil fuels. Sulfur dioxide is a pungent, colorless gas that is produced by volcanic eruptions and burning fossil fuels containing sulfur. Both gases contribute to air pollution and have negative impacts on the environment and human health.
CO2 diffuses faster than SO2 because CO2 molecules are smaller and lighter than SO2 molecules, allowing them to move more quickly through a medium. In addition, CO2 has a lower molecular weight and therefore higher average velocity compared to SO2 at the same temperature, contributing to its faster diffusion rate.
