Chemical kinetics = how fast reaction takes place
thermodynamics -_
whether or not reactions take place
COLLISION THEORY OF CHEMICAL REACTION
rate of reaction =
largely affected by the concentration of reactant and temperature
→ rate ↑ when number of collisions ↑ Is
potential energy =
energy stored in the bonds within and among the particles of the
reactants
kinetic energy __
movement of the particle
activation energy =
minimum amount of energy required to initiate a chemical reaction
