Which of these can be used to speed up a chemical reaction (Select all appropriate answers)

• Increased Temperature

• Increased Volume

• Increased Concentration

• Increased surface area

As time passes the reaction rate starts to...

• Speed up

• Stay the same

• Slow down

• Not change

Increasing the concentration of a reactant will (Two answers)

• Increase the number of particles present

• Decrease the number of particles present

• Decrease the number of collisions

• Increase the number of collisions

Increasing the temperature of a reactant will

• Give the particles more energy

• Give the particles less energy

• Make particles move more quickly

• Make it more likely that particles will collide successfully
