Cornell Notes

Topic: Energy in Chemical Reactions (Exothermic vs. Endothermic)

Date: 5/6/2014

Energy is the ability to do work or produce heat. Kinetic energy = energy of movement Potential energy = energy of position Chemical energy = energy of chemical

reactions

Describe

energy.

Cornell Notes (continued)

Chemical potential energy is the energy stored in the reactants of a chemical reaction.

Cornell Notes (continued)

Compare and

contrast exothermi

c and endother

mic reactions.

Exothermic Endothermic

• A chemical reaction where energy is released (exo = exit)• Reactants Products + HEAT• Examples:• burning• exploding• freezing (liqsol)• condensing(gasliq)• sound• temperature of

surroundings increases

• A chemical reaction where energy is absorbed (endo=indoor)• Reactants + HEAT Products• Examples:• growing• melting (solliq)• boiling (liqgas)• cooking• temperature of

surroundings decreases

Reflection

Answer the following reflection question: Describe one way you would

be able to tell if a chemical reaction was endothermic or exothermic. What does this mean?
