ACSCH070

Collision theory can be used to explain and predict the effect of concentration, temperature, pressure and surface area on the rate of chemical reactions by considering the structure of the reactants and the energy of particles

ACSCH070 | Content Descriptions | Unit 2 | Chemistry | Science | Senior secondary curriculum

ACSCH091

Over time, physical changes and reversible chemical reactions reach a state of dynamic equilibrium in a closed system, with the relative concentrations of products and reactants defining the position of equilibrium

ACSCH091 | Content Descriptions | Unit 3 | Chemistry | Science | Senior secondary curriculum

ACSCH099

The relationship between acids and bases in equilibrium systems can be explained using the Brønsted-Lowry model and represented using chemical equations that illustrate the transfer of hydrogen ions
