Endothermic and Exothermic Reactions

100

In an exothermic reaction energy is ___.

In an endothermic reaction energy is___. 

exo- exit, energy is released 

endo- into, energy is absorbed 

200

What is activation energy?

It is the energy required to break the bonds in the reactants for a chemical reaction to occur. 

300

Is this an endothermic or exothermic reaction? 

2NaHCO₃ + 129kJ (energy) --> Na₂CO₃ + H₂O + CO₂

Energy is on the reactants side so this is an endothermic reaction. 

400

'/;Is this an endothermic or exothermic reaction?

C+ O₂ --> CO₂ + 349 kJ (energy)

This is an exothermic reaction since energy is on the products side

500
