What factors contribute to the deviation of real gases from ideal gas behavior?
✔✔ Real gases deviate from ideal behavior due to intermolecular forces and the finite volume of
gas molecules, which become significant at high pressures and low temperatures.
How can you determine the molecular geometry of a molecule using VSEPR theory?
✔✔ The molecular geometry of a molecule can be determined by applying Valence Shell
Electron Pair Repulsion (VSEPR) theory, which predicts the arrangement of electron pairs
around a central atom to minimize repulsion, leading to specific shapes like linear, tetrahedral, or
trigonal planar.
What is the role of a reducing agent in a redox reaction?
✔✔ A reducing agent donates electrons to another substance, causing the other substance to be
reduced while itself being oxidized.
How do you calculate the equilibrium constant (K) for a reaction given the concentrations of
reactants and products at equilibrium?
1
, ✔✔ The equilibrium constant (K) is calculated by taking the ratio of the concentrations of
products to reactants, each raised to the power of their coefficients in the balanced equation.
What is the difference between an electrolyte and a non-electrolyte in terms of electrical
conductivity?
✔✔ An electrolyte dissociates into ions in solution, allowing it to conduct electricity, while a
non-electrolyte does not dissociate into ions and thus does not conduct electricity.
How does the concept of atomic radius vary across the periodic table?
✔✔ Atomic radius decreases from left to right across a period due to increasing nuclear charge,
which pulls electrons closer to the nucleus, and increases from top to bottom within a group due
to additional electron shells.
What is the significance of the Gibbs free energy change (ΔG) in predicting the spontaneity of a
reaction?
✔✔ The Gibbs free energy change (ΔG) indicates whether a reaction is spontaneous; a negative
ΔG signifies a spontaneous reaction, while a positive ΔG indicates a non-spontaneous reaction.
How does the addition of a common ion affect the solubility of a salt in a solution?
