What is chemical kinetics?
The study of how fast chemical reactions occur.
The study of the kinds of chemical reactions.
The study of the kinetic energy in an atom.
The study of redox and acid base reactions.
In order for a chemical reaction to occur, to particles must (a) with sufficient (b) and proper (c)
Increase in temperature causes the particles to
slow down
move faster
stay apart from each other
move in the correct order
Why does a higher temperature increase the rate of a reaction?
It increases both the frequency collision and energy of reactant particles
It only increases the frequency of collision
It only increases the energy of reactant particles
It reduces the activation energy of the reaction
