EXO AND ENDOTHERMIC REACTIONS
DURING A CHEMICAL REACTION
Bonds in reactants must be broken
absorbs energy
New bonds must be made to form the product
releases energy
Exothermic reactions
involves the transfer of energy from the reacting chemicals to their surroundings
heats up the surroundings
You measure the temperature rise as the reaction happens
More energy is released when bonds are made then what is absorbed to break them
In an exothermic reaction:
The products are at a lower than the reactants
Therefore it get from reactants to products energy is released
temperature increases in the surroundings
Exothermic reactions
Transfer energy from their surrounding to the reacting chemicals
Take in energy causing a drop im temperature
much less common than exothermic
More energy absorbed breaking bonds than is released when bonds are amde
In an endothermic reaction
the products are at a higher energy than the reactants.
energy is absorbed
temperature of the surroundings decrease
