Define: Activation Energy |
Minimum energy needed to start a reaction |
|
|
Define: Endothermic Reaction |
Reaction that transforms thermal energy into chemical potential energy |
|
|
Define: Exothermic Reaction |
Reaction that transforms potential chemical energy into thermal energy |
|
|
What effect does endothermic reactions have on temperature? |
It causes a temperature decrease of reaction mixture |
|
|
What effect does exothermic reactions have on temperature? |
It causes a temperature increase of reaction mixture |
|
|
Give two examples of Exothermic Reactions |
-respiration -combustion |
|
|
Define: Activated Complex |
A high energy, unstable, temporary transition slate between products and reaction. |
|
|
Define: Reversible Reactions |
A reactions in which the products can be converted into reactants |
|
|
Define: Heat of Reaction/ Enthalpy Change |
Net change in chemical potential energy of the system |
|
|
Define: Bond Energy |
Amount of energy required to break or release a bond in KJ.mol-¹ |
|
|
How do you calculate ACTIVATED ENERGY |
Ea = Ecomplex - Ereactants |
|
|
How to calculate Heat of Reaction |
📐H = Eproducts - Ereactants |
|
|
How to calculate Eabsorbed |
Eabsorbed = Ecomplex -Ereactants |
|
|
How to calculate Ereleased |
Ereleased = Ecomplex - Eproducts |
