Week 1 Learning Tool Reaction Rates

What does it mean when a reaction is catabolic?

• It means the reaction involves the formation of molecules to store energy.
• It means the reaction has no impact on energy levels.
• It means the reaction involves the release of water.
• It means the reaction involves the breakdown of molecules to release energy.

What are the four factors that affect the reaction rate?

• Temperature, concentration, surface area, and presence of a catalyst
• pH, solubility, viscosity, and conductivity
• Density, mass, weight, and length
• Color, pressure, volume, and time
