Rates Of Reaction Flashcards
Give the formula for finding the rate of reactions
Time
How can you find the rate of a chemical reaction
By measuring the amount of a reactant used of the amount of product formed over time
When can chemical reactions only occur?
When reacting particles collide with each other and with sufficient energy
The minimum amount of energy particles must have to react, this is called…
The activation energy
What happens when you increase the temperature
It increases the speed of the reacting particles so they collide more frequently and energetically
INCREASES RATE OF REACTION
What happens when you increase the pressure of reacting gases
It increases the frequency of collisions.
INCREASE THE RATE OF REACTION
What happens when you increase the concentration of reactants in solution
It increases the frequency of collisions
INCREASING RATE OF REACTION
What happens when you increase the surface area of solid reactants
It increases the frequency of collisions
INCREASING RATE OF REACTION
what happens to catalysts
They change the rate of chemical reactions but are not used up during he reaction
what to different reactions need
Different catalysts
Why are catalysts important in increasing the rates of reactions
They are used in industrial processes to reduce costs
