Question

Rachel is using a Bunsen burner to heat a solution. Which of the following would let her control the rate of reaction in the solution? A. replacing the amount of flammable gas used with different rates B. controlling the amount of air entering the combustion tube C. placing the burner in open surroundings

Answer 1

Answer: b) controlling the amount of air entering the combustion tube

The rate of a reaction when using a Bunsen burner is changed by modifying the temperature of the flame.

In this type of burner, the temperature of the flame is modified by controlling the amount of air available for the flame. More air allowed will result in a hotter flame. This is achieved by turning the collar around the air holes.
