pressure

The energy needed for a reaction to occur

The minimum amount of energy needed for a reaction to potentially occur

The energy added by a catalyst

The energy possessed by the products

Slow collision frequency

Allow less effective collision between the particles

Cause particles to lose speed

Increase collision between the particles thus increasing the rate.

Gaseous reactants

Solid reactants

Liquid reactants

None of the above

It makes particles move faster

It increases the likelihood of collisions with the correct geometry

It decreases the surface area available to react

It increases the number of collisions
