rate of change Flashcards
what are the factors that affect rate of reaction
concentration, pressure, temperature, surface area, catalyst
ADS and DISADS of catalysts
ADS- cost effective, reduces burning of fossil fuels/energy
DISADS- toxic
what directions do reactions happen in dynamic equilibrium
both forward and backward
what happens to concentration of reactants/products in dynamic equilibrium
remains constant
what is a closed system
reactants/products can not be added/removed
what is la chateliers principle
if any of the conditions of a reversible reaction at equilibrium are changed, the system will adapt to counteract it.
what will happen to position of equilibrium if you increase temperature
shift in endothermic direction (more endo products produced than exo)
what will happen to position of equilibrium if you decrease temperature
shift in exothermic direction (more exo products produced than endo)
is the forward reaction endo or exo
endo
what will happen to position of equilibrium if you decrease pressure
shift to side of reaction that produces most gas molecules
what will happen to position of equilibrium if you increase pressure
shift to side of reaction that produces least gas molecules
what will happen to position of equilibrium if you increase concentration of reactants
shift to products
what will happen to position of equilibrium if you increase concentration of products
shift to reactants
