What is an Exothermic reaction?
A reaction where energy exits the reaction (it gets hot)
EXOthermic, what happens to the energy in the reaction?
What is an endothermic reaction?
A reaction where energy enters the reaction (it gets cold)
ENDOthermic, what happens to the energy in the reaction?
What are two examples of an Exo and Endothermic reaction (one each)
Exothermic: HCL + Magnesium ribbon
Endothermic: NaHCO3 + citric acid
Think elements
Describe energy profile diagrams for both endo and exothermic reactions, labeling the energy change and the progress of reaction. (Draw in head if possible)
Exothermic: y-axis= energy change
X-axis= progress of reaction reactants straight line at the top, goes up to a dome and then drops to a straight line labeled products
Endothermic: (same x and y-axis)
Reactans straight line at bottom, rises up to a dome and then drops a little to a straight line of products
Think x and y-axis and what the graph would look like in energy change (ENDO? EXO? What happens to the energy?)
Describe what is meant by activation energy
Activation energy is the minimum amount of energy for particles to react
