I can draw, label and interpret reaction profiles for exothermic and endothermic reactions, and understand the changes these cause in the surroundings.
Show transcript
A reaction profile compares the amount of energy the products of a reaction have compared to the reactants.
Exothermic chemical reactions transfer energy from reactants to the surroundings causing an increase in temperature.
Endothermic chemical reactions transfer energy from the surroundings to the products causing a decrease in temperature.
Activation energy is the minimum amount of energy transferred to reactants that allows a chemical reaction to start.
