Rates Of Reaction Flashcards
(10 cards)
What is the rate of a chemical reaction?
How fast the reactants are changed into products.
The x on a graph is usually ____________
Amount of product formed
The y on a graph is usually __________
Time
The steeper the line on the graph the ________________________________
The faster the rate of reaction
Over time the line becomes less steep as the reactants are ____________
Used up
Collision theory is?
That a reaction will only take place when particles collide (crash into each other)
Why won’t the particles react when they collide?
They don’t have enough energy.
What is the minimum energy the particles need to react called
Activation energy
The more often the particles collide the _______ their reaction will happen
Faster
What four things does the rate of reaction depend on?
Temperature, surface area, concentration, catalyst
