Question
A student mixed baking soda and vinegar and observed that the reaction was endothermic. When is a reaction endothermic?
- When it is reversible
- When it can be repeated
- When heat/energy is released by the process
- When it requires heat/energy to make it happen
Hint:
The energy is absorbed in the endothermic reaction.
The correct answer is: When it requires heat/energy to make it happen
