Rates Of Reaction Flashcards
What 5 aspects can effect the rate of a reaction
Why do we use these
Temperature Concentration of solution Gas pressure Surface area of solid Catalyst
Reduce cost in industry
What two equations can be used to meshed the rate of a reaction.
Time
Time
How do reaction occur and what is activation energy
Reacting particles collide with each other at sufficient energy
Minimum amount of energy particles must have to react
What Is the effect of increasing a reaction temperature
Increases the frequency that particles collide due to more energy- increases reaction rate
How can increasing the pressure of reacting gases effect the reaction
Increased frequency that particles collide so increase reaction rate
Increasing concentration of reactants does what to a reaction and why
Increases frequency of particle collision so increase rate of chemical reaction
Increasing the surface area of solid reactants does what to a reaction and why
Speeds up reaction rate as increases the frequency of particle collisions.
How are catalysts used in reaction
Change rate of reaction however not always used up
Different reactions need different catalysts
Why are catalysts important
Increase rate of chemical reaction so reduce cost in industry
