Chapter 8 Flashcards
Effect of conditions on rate:
TEMPERATURE
Increase and Decrease.
Effect of conditions on rate:
RATE #1
Increase - more kinetic energy, more chances of collisions
Decrease - less kinetic energy, fewer chances of collisions.
Effect of conditions on rate:
PRESSURE/CONCENTRATION RATE
Increase - more particles to collide
Decrease - less particles to collide.
Effect of conditions on rate:
SURFACE AREA
Increase and decrease.
Effect of conditions on rate:
RATE #2
Increase - more particles available to react
Decrease - less particles available to react
Effect of conditions on rate:
CATALYST
Present and Non-Present.
Effect of conditions on rate:
RATE #3
Faster, provides an alternative route with a lower activation energy.
Slower.
Reversible
A reaction that can turn reactants into products and products into reactants.
Dynamic equilibrium
A reaction in which the forwards and backwards reactions occur at the same rate and the concentrations of reactants and products are constant.
Forwards reaction
The reaction that is forming products from reactants.
Backwards reaction
The reaction that is forming reactants from products.
Exothermic
A reaction that releases heat energy to the surroundings.
Endothermic
A reaction that takes in heat energy to the surroundings,
Rate of reaction
Change in concentration of reactants or products over unit time.
Catalyst
A substance that is not used up that provides an alternative pathway for a reaction to with a lower activation energy, speeding up the rate of reaction.
