When you strike a match, what do you provide that enables the flame to appear?
a. catalyst
b. reactant
c. product
d. activation energy
e. activated complex

Explanation:

The minimum amount of energy required by a substance to begin a reaction is known as the activation energy.

Therefore, we can conclude that when you strike a match, you provide activation energy that enables the flame to appear.

Whereas a catalyst helps in increasing the rate of reaction but it does not start the reaction. On the other hand, when reactants combine together then we get products.

Thus, we can conclude that options (a), (b), (c), and (e) are not correct.

Hence, option (d) is the correct answer.
