CHEM 210 EXAM 8 2026 KINETICS RATE
LAW ANALYSIS ACTIVATION ENERGY
ARRHENIUS EQUATION MODELLING
◉ Water of hydration
Answer: the attraction between ions and water is so strong that for
many solids, water molecules are a part of
the crystal structure.
◉ Electrolyte
Answer: a substance that conducts electric current when
dissolved in water. A substance that does not conduct electricity is
called a non-electrolyte.
◉ Strong electrolyte
Answer: a compound that dissociates completely to
ions in an aqueous solution
◉ Weak electrolyte
Answer: a compound that only partially dissociates to ions in an
aqueous solution
, ◉ Colligative property
Answer: any property of a solution that depends on the number of
solute particles, and not on the nature of the particles
◉ Important colligative properties...
Answer: - Freezing-point depression
• Boiling-point elevation
• Osmosis
◉ Chemical kinetics
Answer: the study of the rates of chemical reactions
◉ Reaction rate=
Answer: change in concentration /change in time
◉ Factors that affect rates of chemical reactions
Answer: Molecular collisions
Activation energy
Endothermic/ Exothermic rxns
Nature of the reactants
Concentration of the reactants
Temperature
