what affects the rate of reaction-what ever affects the number of successful collision per unit time NSCPU
-
pressure
-
high pressure
There are more particles per unit volume and there are more number successful collision per unit time
the reaction is faster as the particles have less distance between them so it takes less time For particles to collide
low pressure
-
-
The reaction is slower as there is more distance between particles so it takes more time to successfully collide
concentration
high concentration
-
-
-
the reactions are also faster as there are more reactants at the begining so the reaction is more rapid
low concentration
-
-
-
the reactions are also slower as there are less reactants at the begining so the reaction is less rapid

-
Catalysts
chemicals that are used to speed up reactions but are used up by providing an alternative route of lower activation energy
examples include
-
-
nano particles
make catalyst far more effective as they have more sites for number successful collision per unit time
