What sign does ΔH have for an exothermic reaction?
Negative (−)
What is an endothermic reaction?
Absorbs heat from the surroundings. The surroundings become colder.
Where is heat in an endothermic reaction?
With the reactants:
Reactants + heat → Products
Which has more energy in an endothermic reaction?
Products have more energy. Reactants have less energy.
What sign does ΔH have for an endothermic reaction?
Positive (+)
