#1
Front (Question)
How does increasing the concentration affect the rate of reaction?
Back (Answer)
There are more particles in a fixed volume This increases frequency of successful collisions Therefore the rate of reaction increases
#2
Front (Question)
How does increasing the pressure affect the rate of reaction
Back (Answer)
There are more particles in the fixed volume This increase the the frequency of successful collisions Therefore the rate of reaction will increase
#3
Front (Question)
How can you investigate the effect of changing concentration?
Back (Answer)
Reacting marble chips with different concentrations of HCL You can find the rate of the reaction by plotting the volume of CO2 gas given off as the reaction progresses over a given time
