Kinetics And Equillibrium Flashcards
Collision theory states
A reaction will most likely occur if reactant particles collide with the proper energy and orientation
Rates of reaction depend on…
Temperature, concentration, nature of reactants, surface area, and presence of catalyst
Equilibrium is when
The rate of forward and reverse reactions are equal
LeChatelier stressors on systems include…
Pressure, volume, temperature, concentration
Potential energy diagrams illustrate…
Energy being absorbed or released
Heat of reactions equals…
Potential energy or products minus the potential energy of the reactants
Positive heat of reaction implies an
Endothermic reaction
Negative heat of reaction implies an
Exothermic reaction
A catalyst provides…
An alternative pathway for a chemical reaction, lowering the activation energy
Adding a catalyst…
Increases both the forward and reverse reaction rate making no shift in equilibrium
Entropy is…
Randomness or disorder in a system. A system with greater disorder has greater entropy
Systems in nature tend to undergo changes toward…
Lower energy and higher entropy
