Question

What can you conclude from the graph?

Answer 1

I believe the answer is: A) do you reaction that causes a firework to explore requires less energy just start and occurs more rapidly than the reaction that causes the candle to burn

The energy needed to start the reaction should be shown by the bump at the begining of the reaction. The bump shown by blue line(candle) is much higher than bump made by the orange line(firework).

The y segment of the graph showing the time. The reaction of firework also happens more rapidly which shown by the fact that the orange line(firework) is always on the left of the blue line(candle).

Answer 2

, burning both the candles and the fireworks involve chemical reactions - the conversion of both substances to ash. So right away, you know that the reactants and the products of both reactions are different. You also know that burning a candle and fireworks both release heat. The reaction is exothermic. That means that the reactants have a higher potential energy than the products. You also know that neither the candle nor the fireworks burn spontaneously - that the reactions won't go unless you've put in some energy in the form of a spark - so for both reactions your energy diagram should show an energy barrier.
