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.

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.
