What is an exothermic reaction?
Think of a reaction where heat is felt or seen.
Name a common example of an endothermic reaction.
It involves plants and sunlight.
What defines an exothermic reaction?
Think about heat flow.
Is photosynthesis endothermic or exothermic?
Focus on energy absorption.
Explain how energy transfer during combustion aligns with exothermic reactions. Provide a relevant chemical equation and analyze the enthalpy change.
Focus on the energy release and check the signs of ΔH.
A reaction has an enthalpy change of +75 kJ. Discuss its implications in a practical context, such as in cooling systems.
Relate it to real-world applications of heat absorption.
