Kinetics Flashcards
Kinetics is
The rate of reaction
Collision theory
Atoms need to collide with sufficient force and proper orientation for reaction to occur
Five factors that a chemical reaction depends on
Temperature, concentration, surface area, nature of reactants, catalyst
Increasing temperature equals
More successful collisions
How does a catalyst affect the rate of reaction
Provides an alternate reaction pathway
Lowers the activation energy
Heat of reaction
∆H = P.E. products - P.E. reactants
(PEP - PER)
Potential energy equals
Stored energy
Exothermic reactions are
Spontaneous
The catalyst does what to a reaction
Speeds it up
What is increasing the pressure in gases REALLY
Increases concentration
What do all the five factors that a chemical reaction depends on cause
More successful collisions
Equilibrium equals
The rate of the forward reaction equals the rate of the reverse reaction
Equilibrium
The concentrations of reactants and products remain constant at equilibrium
LaChatelier’s principle
Which way will the rate shift if stress is applied
Decrease in heat favors the…
Exothermic
