Your teacher asks you to mix two compounds to find out if the reaction is endothermic or exothermic
What will you do to determine which type of reaction is occurring?

5
You are investigating the reaction rate of a chemical reaction
How might the required activation energy be affected if you add a catalyst to the reaction? If you add a inhibitor to the reaction?

Answer 1

If the resulting compound feels hot, then it is exothermic. Otherwise, it is endothermic.

Catalysts and inhibitors both affect the reaction rate of a chemical reaction. A catalyst speeds up the rate of reaction, while an inhibitor does the opposite (slows down the reaction rate).
