Activation Energy Flashcards
Activation energy (Ea) is the minimum amount of _
Energy needed to start a chemical reaction
The lower activation energy _
Faster reaction will proceed
Every molecule has its own minimum amount of _
Kinetic energy
Collision must have enough energy to _
Overcome the activation energy needed for reaction
Reaction must also possess enough _ to break bonds between molecules so they can react
Free energy
Activation energy is related to _
Free energy
Gibbs free energy is difference in
Energy between products and reactants
Activation energy is also related to _
Activation Enthalpy
Activation Enthalpy represents difference in energy between reactants at their _ and _ in a reaction
Normal state
Transition state
As activation energy and Enthalpy decreases _
Reaction has less chance of occurring
