55-58 - Rate of Reaction Flashcards
What four things affect the rate of reaction?
Temperature
Concentration/pressure
Catalyst
Surface area
How do you calculate the rate of a reaction?
Reactant used or product formed / time
What three things can be used to measure the rate of reaction?
Precipitation
Mass change
Volume of gas given off
How do you measure a reaction’s speed with precipitation?
Time until a mark isn’t visible through the solution anymore
How does surface area speed up the rate of reactions?
More frequent collisions
What are the control variables when the concentration is being changed?
Amount of other reactant
Volume of acid
Temperature
Which method of calculating the rate of reactions cannot make a graph?
Judging by precipitation
What is the usual X axis on a graph of the rate of reaction?
Time
