A metal-treatment furnace burns a solid fuel. Before the air supply is increased, a technician analyses the gases leaving the furnace.
| Gas | Detected in the initial sample? |
|---|---|
| Carbon monoxide | Yes |
| Sulfur dioxide | Yes |
The same mass of the same fuel is burned each minute. The air supply is then increased until there is a plentiful supply of oxygen.
A supervisor claims that both gases in the initial sample were produced because the furnace did not have enough oxygen.
Evaluate the supervisor's claim.
After the air supply is increased, predict how the amounts of carbon monoxide and sulfur dioxide produced each minute compare with the amounts produced before the change.
Explain your answer.
