PPT-The Collision Theory and Activation Energy

Explaining how and why factors affect reaction rates The MaxwellBoltzmann apparatus Maxwell and Boltzmann performed an experiment to determine the kinetic energy distribution of atoms Because all atoms of an element have roughly the same mass the kinetic energy of identical atoms is determined by velocity KE . . and Chemical Equilibrium.
