Energy Transfer, Catalysts & Reversible Reactions Flashcards
Is bond breaking endothermic or exothermic?
Endothermic
Is bond formation endothermic or exothermic?
Exothermic
What is the formula for the overall energy change in a reaction?
Energy required to break bonds
(minus)
Energy released by forming bonds
How do catalysts work?
By lowering the activation energy by providing alternative routes
What is reversible reaction?
one where the products of the reaction can themselves react to produce the original reactants
When can reversible reactions reach dynamic equilibrium?
In a closed system
What is the definition of a dynamic equilibrium?
Where the reactions are still taking place in both directions but the over all effect is nil because the forward and reverse reactions cancel eachother out.
