Q
Q: In an endothermic reaction, what is the sign of ΔH?
Solution:
In an endothermic reaction, heat is absorbed, resulting in a positive change in enthalpy (ΔH > 0).
Steps: 5
Show Steps
Step 1: Understand what an endothermic reaction is. It is a type of reaction that absorbs heat from its surroundings.
Step 2: Know that when a reaction absorbs heat, it requires energy to proceed.
Step 3: Recognize that the change in enthalpy (ΔH) measures the heat content of a system.
Step 4: Since heat is absorbed in an endothermic reaction, the change in enthalpy (ΔH) becomes positive.
Step 5: Conclude that in an endothermic reaction, ΔH is greater than 0 (ΔH > 0).
