Grade 11 Chemistry

Students began their exploration of Structure 1.1: The Particulate Nature of Matter, establishing foundational models of particle behavior. The class focused on kinetic molecular theory to explain state changes, distinguishing between macroscopic observations and microscopic particle arrangements, and analyzing phase change behavior on heating curves to understand how thermal energy affects particle kinetic and potential energy. Next week we will explore various physical techniques used in separating mixtures.

Students concluded the Reactivity 1 (SL) thermochemistry module by applying Hess’s Law to construct enthalpy cycles and calculate indirect enthalpy changes. They extended these principles to real-world energy choices by evaluating fuels—comparing the high energy density yet heavy carbon impact of fossil fuels (coal and petroleum) against sustainable alternatives like hydrogen and methanol fuel cells.

We begin R2-Rates of reactions this coming week.

HL students began exploring the Bon-Haber cycles and will continue with entropy and Gibbs free energy next week.
