Questions & Step-by-Step Solutions
In an endothermic reaction, what happens to the enthalpy of the system?
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 energy within the system increases.
Step 3: Know that enthalpy is a measure of the total energy of a system, including internal energy and the energy required to make room for it by displacing its environment.
Step 4: Since the system absorbs heat in an endothermic reaction, the enthalpy of the system increases.
Step 5: Conclude that in an endothermic reaction, the change in enthalpy (ΔH) is greater than zero (ΔH > 0).
