Unit 1 - Part 1 - Rates of Reaction Flashcards
If the temperature of a reaction increases, the reaction rate…
Increases
Does increased particle size increase or decrease the rate of reaction?
Decreases the rate of reaction
What does adding a catalyst do to a reaction?
It increases the reaction rate
What does increasing the concentration of a reaction do?
Increases the reaction rate
Do catalysts appear in word equations?
No, they don’t
How many times can a catalyst be used?
An infinite amount of times
Are catalysts used up during a reaction?
No, they are never used up in are in a reaction
What are enzymes?
They are biological catalysts
How can you measure if a reaction has taken place? Name 4 examples.
Mass, colour, smell, volume, pH, electrical conductivity, pressure or concentration
What is the equation for reaction rate?
Change in quantity divided by the change in time
