Answer 2

The reaction of an exploding firework occurs  at a faster rate than a burning candle.

Statement (b) is true.

Explanation:

• The reaction of an exploding firework occurs at a faster rate than a burning candle.
• It is because of the number of chemical reactions that are taking place during the explosion of a firework.
• A small amount of activation energy is enough to start the combustion of chemical compounds inside the firework.
• Most of the salt compounds are in powdered form and they catch the heat energy as quickly as possible.
