Unit 7 – Industrial Application of Catalysis

How does a catalyst work in speeding up a reaction?

• By lowering the activation energy or reaction

• by giving them more energy

• by making them more available

The minimum amount of energy needed for colliding particles to react is called the

• Chemical Energy

• Kinetic Energy

• Activation Energy

• Potential Energy

A substance that increases the rate of a reaction without being used up during the reaction is called a

• catalyst

• product

• reactant

• solute

Catalysts permit reactions to proceed along a ___________energy path.

• lower
• higher

A catalyst increases the efficiency of collisions between reactants.

• true
• false
