Question

The graph below compares the rates of reaction of a burning candle and an exploding firework.


What can you conclude from the graph?

The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn. The reaction that causes a firework to explode requires less energy to start, and occurs less rapidly than the reaction that causes a candle to burn. The reaction that causes a firework to explode requires more energy to start, and occurs less rapidly than the reaction that causes a candle to burn. The reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn.

Answer 1

Answer: The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn

Explanation: As can be seen from the energy diagram, the reaction which leads to burning of candle and shown by a blue curve require higher activation energy , i.e energy required to cross the energy barrier and get converted to products. It also takes more time for completion.

The reaction which leads to exploding firework and shown by a orange line and requires less activation energy , i.e energy required to cross the energy barrier and get converted to products. It takes less time for completion.

Answer 2

The reaction that causes a firework to explode requires less energy (activation energy) to start.

What is activation energy?

The term activation energy refers to the energy that is required for a reaction to start. The activation energy is usually supplied externally such as using a spark.

We can see from the graph that the reaction that causes a firework to explode requires less energy (activation energy) to start, and occurs less rapidly than the reaction that causes a candle to burn.
