Does it give off heat or absorb heat?
What type of reaction absorbs heat?
Consider if the surroundings get warmer or cooler.
In a reaction coordinate diagram, where do the products appear for an exothermic reaction?
Think about the energy changes during combustion.
Calculate the enthalpy change for a hypothetical endothermic reaction where the reactants start at 150 kJ and the products end at 300 kJ.
Remember the formula for calculating ΔH.
Discuss the practical implications of understanding exothermic and endothermic reactions in industrial applications.
