List four factors that affects the rate of a reaction
temperature
concentration
surface area
volume
catalysts
A temperature increase causes the particles ......
to slow down
move faster
collide higher
in the right order
How does a catalyst work in speeding up a reaction?
By lowering the activation energy or reaction
by giving them more energy
by making them more available
Why does a higher concentration increase the rate of reaction?
it increases the amount of reactants
it lowers the activation energy
it increases the energy of particle collisions
it increases the frequency of particle collisions
Why does a higher temperature increase the rate of a reaction?
it increases both the frequency and energy of particle collisions
it only increases the frequency of particle collisions
it only increases the energy of particle collisions
it reduces the activation energy of the reaction
The minimum amount of energy needed for colliding particles to react is called
Chemical Energy
Kinetic Energy
Activation Energy
Potential Energy
