LWB Level 2 Chemical Reactivity 2.6 Learning Workbook

Master the dynamics of chemical reactions with this specialized NCEA Level 2 Chemistry resource. This workbook is designed for the 2.6 External Achievement Standard, focusing on the factors that influence reaction rates and the delicate balance of chemical equilibrium.

Key Features

• Standard Focused: Fully aligned with the requirements of NCEA Chemistry Achievement Standard 91166 (Chemistry 2.6).

• Collision Theory: Detailed exploration of how particle concentration, surface area, temperature, and catalysts affect the rate of reaction, using the collision theory model to explain observations.

• Chemical Equilibrium: Clear explanations of reversible reactions and the dynamic nature of equilibrium, including how to write and use equilibrium constant ($K_c$) expressions.

• Le Chatelier’s Principle: Step-by-step guidance on predicting and explaining how changes in concentration, pressure, and temperature shift the position of equilibrium in gaseous and aqueous systems.

• Acids and Bases (Systems): Introduction to the properties of strong and weak acids/bases, including $K_w$ calculations, pH, and the species present in various solutions at equilibrium.

• Scientific Literacy: Provides the specific terminology and logical frameworks required to construct the high-level "link and explain" arguments necessary for Merit and Excellence.

• Exam Preparation: Packed with NCEA-style questions, data interpretation tasks, and practice graphs to ensure students are fully prepared for the external examination.
