Test Your Knowledge on Chemical Reactions and Reaction Rates!

Chemical Reactions and Factors Affecting Reaction Rates

• There are two types of changes: physical and chemical.
• Physical changes affect only the physical appearance of a substance, while chemical changes make a new substance.
• Five signs of a chemical change are color change, odor change, new gas or solid formation, gain or loss of energy, and difficulty in reversing the change.
• A mixture is formed when two or more substances are combined without chemical bonding.
• Homogeneous mixtures have evenly distributed substances while heterogeneous mixtures do not.
• A solution is a mixture where one substance dissolves in another.
• Solubility measures how much solute can dissolve in a liter of solvent.
• An unsaturated solution has not reached its concentration limit, while a saturated solution has.
• Endothermic reactions absorb energy from their surroundings and feel cool, while exothermic reactions release energy and feel warm.
• Activation energy is the minimum extra energy required for a molecule to convert into a product.
• There are five basic types of chemical reactions: combination, decomposition, single replacement, double-replacement, and combustion.
• Reaction rates can be affected by temperature, concentration, surface area, catalysts, and inhibitors.
