MATCH QUESTION

1 min • 10 pts

Match the following Reaction Rate affect with the definition of why it speeds up reactions.

Temperature

This substance speeds the reaction rate by lowering the activation energy needed to start the reactions

Surface Area

Higher amounts of this of this leads to more frequent collisions between reactant particles

Pressure

The higher the ______, the faster the reaction because more particles are moving and colliding, thus contacting with each other to react.

Catalyst

The more of this causes there to be more room for the particles to collide and react with one another

Concentration

The higher the ____ = the smaller of the volume, causing more particle collisions
