Overview
Concentration and thermodynamic properties are fundamental concepts in chemistry that help us understand how substances behave in different environments. Concentration measures how much of a substance is present in a solution, while thermodynamics deals with energy changes during chemical reactions....
Key Terms
Example: A 1 M (molar) solution has 1 mole of solute in 1 liter of solution.
Example: Thermodynamics helps explain how engines convert heat into work.
Example: In a saturated solution, the rate of dissolution equals the rate of crystallization.
Example: Adding more reactant shifts the equilibrium to produce more products.
Example: A 0.5 M NaCl solution contains 0.5 moles of NaCl in 1 liter of water.
Example: The enthalpy change during a reaction indicates whether it is exothermic or endothermic.
