Sample Question
Explain how evidence from first ionization energies across periods accounts for the existence of main energy levels and sub-levels in atoms.

Ionisation energy: The energy that is required (or given out) to overcome the attraction of the nuclear charge and remove an electron from a gaseous atom. Removing 1 electron results in a +1 charge. Main (or principal) energy levels, sub-levels and orbitals: The main energy levels, n are assigned whole number integers, n = 1, 2, 3, 4... . n = 1 represents the lowest energy level. Each main energy level contains n sub-levels and a total of n^2 orbitals. The magnitude of the ionisation energy will depend on the charge on the nucleus. The more electrons that have been removed from an atom, the greater the energy required to remove the next electron. When the successive electrons are all in the same energy level this is because of a reduction in the amount of electron-electron repulsion and hence the greater nuclear-electron attraction that results causes the remaining electrons to move closer to the nucleus.

The number of protons in the nucleus influences the ionisation energy.

Sub-levels and orbitals are primarily determined by the number of neutrons in an atom.

The atomic mass of an atom affects its sub-levels and orbitals.

IB Chemistry HL: Chemical Kinetics and Reaction Mechanisms

Questions: 5 | Attempts: 13 | Last updated: Aug 4, 2025

Sample Question
Distinguish between the terms rate constant, overall order of reaction and order of reaction with respect to a particular reactant.

Rate expression: The rate constant is the sum of the orders of the individual reactants. Order of reaction: The rate expression shows the proportionality between the reaction rate and the concentrations of the products.

Rate expression: The order of reaction is as follows: m + n = overall order Rate constant: The constant represents the concentration of the reactants multiplied by the rate of the reaction.

Rate expression: The concentrations of the reactants to the power of the order of each product multiplied by the rate constant: Rate=k[A]m[B]n[C]o Order of reaction: The order of reaction is said to be m for substance A, n for substance B, etc. The total order of reaction is the sum of these powers, ie m + n etc = overall order Rate constant: The constant in the above equation represents the proportionality between the reaction rate and the concentrations of the reactants. Its units depend on the number of reactants and their orders.

Order of reaction: The overall order of reaction is the proportionality constant between the concentration of the reactants and the rate of the reaction. Rate constant: The total order is the sum of the powers of the concentration terms.
