Rate of reaction Flashcards
(13 cards)
What factors affect the rate of reaction?
Concentration or pressure
Surface area
Temperature
Catalysts
What is the collision theory?
Explains how factors affect rate or reaction
If you increase one of the factors, what happens to rate of reaction?
It increases
What are catalysts?
they increase the rate of reaction by providing an alternate pathway for reaction that requires less energy
What is a reversible reaction?
When products from a reaction can turn back into reactants.
What is the equation for the rate of reaction?
rate of reaction = amount of reactant used or made / time
What happens if temperature is increased?
Particles move faster and collide more frequently, which increases rate of reaction.
If surface area is great, what happens to rate of reaction?
Rate of reaction is greater, because more particles are exposed and so are more likely to have successful collisions
What is dynamic equilibrium influenced by?
Temperature
Concerntration or pressure
What is dynamic equilibrium?
Where there is no overall charge in amount of products or reactants if reactions are ongoing.
If temp is increased, what happens to equilibrium?
Shifts to endothermic direction
Shifts to decrease temp
If temp decreases, what happens to equilibrium?
Shifts in the exothermic direction
Shifts to increase the temp
What happens to equilibrium if concentration increases?
