Question: Which of the following is true for an endothermic reaction?

Options:

Correct Answer: ΔH is positive

Solution:

In an endothermic reaction, heat is absorbed, resulting in a positive ΔH.

Which of the following is true for an endothermic reaction?

Which of the following is true for an endothermic reaction?

Step 1: Understand what an endothermic reaction is. It is a type of chemical reaction that absorbs heat from its surroundings.
Step 2: Recognize that when heat is absorbed, the temperature of the surroundings decreases.
Step 3: Learn about ΔH, which stands for the change in enthalpy (heat content) during a reaction.
Step 4: In an endothermic reaction, since heat is absorbed, the value of ΔH is positive.
Step 5: Conclude that in an endothermic reaction, heat is absorbed, leading to a positive ΔH.
