5
Q
how do you work out the mean rate of reaction
A
time taken
6
Q
what creates a greater rate of reaction
A
a higher frequency of successful collisions
7
Q
what happens if the concentration of the solution is higher
A
the reacting particles get more crowded
higher rate of collisions
rate of reaction increases
8
Q
how do you work out the rate of reaction from a graph
A
change in time
9
Q
name three things the rate of a reaction
A
the temperature
the concentration
the physical sate of the reactants
