A temperature increase causes the particles ......
to slow down
move faster
collide higher
in the right order
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
