Collision Theory (3)

Chemistry

Not quite remember

I easily remember

Activation Energy (5)

Different reactions have different activation energy

Example of activation energy

Activation energy is like the energy a horse required for a horse to overcome the barrier

Activation Energy (6)

The activation energy is represented by the symbol Ea

Collision Orientation (1)

Reactant particles must be in a specific orientation to result in effective collisions

Collision Orientation (2)

If the reactant particles collide in incorrect orientations, the particles will bounce back and no reaction occurs

The collision between reactant particles in the correct orientation

The collision between reactant particles in the wrong orientation

Rate of Reaction (1)

The rate of reaction depends on the rate of successful collisions between the reactant particle

Rate of Reaction (2)

The higher the frequency of collision between reactant particles with enough energy and in the correct orientation, the faster the reaction occurs

Rate of Reaction (3)

The rate of reaction depends on the frequency of effective collisions
