Questions & Step-by-Step Solutions

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.
