Rate Of Reaction Flashcards
What happens if a reaction happens slowly
A low rate of reaction
Mass of a substance
Solid
Liquid
Gas
Volume of gas
It can be measured by a measuring cylinder
What’s the rate of reaction formulae
Amount of reaction used or produced
——————————
Time taken
If the rate of reaction increased
A catalyst is used
Temperature increased
Collisions
For a chemical reaction to occur the reactant particles must collide
If pressure of the reacting gas increased
Rate of reaction increased
Greater chance of particles colliding
Without a catalyst
More collisions result in a reaction, so the reaction needs different catalysts
Why are catalysts important?
They reduce cost
What are the factors of changing a rate of reaction?
Temperature
Concentration
Pressure
Surface area
What is the rate of reaction formula?
Reactant used
_________________
Time
When will reactions only collide?
When particles have enough energy
What happens when the temperature rises?
More energy Occurs
Increases speed of the particles
Collide more
What happens if the pressure increases
Increases frequency of collisions which increases rate of reaction
What has syringe used for
Measuring the volume of gassed produces
