Chemistry - Secondary V Optional Program

Reaction rate

Studying reaction rates gives students the opportunity to acquire scientific and technical knowledge of phenomena and applications1 in which these rates are crucial.

Over the course of their secondary school education, students have explored increasingly complex phenomena, problems and applications. They have acquired knowledge related to The Material World, The Living World, The Earth and Space and The Technological World. By using the experimental method, modelling and carrying out analysis, they are able to describe, understand and explain the laws and models governing reaction rates. Students learn to apply this new knowledge in a variety of contexts to explain phenomena or make predictions. In this way, they acquire a better understanding of the importance of reaction rates in the world around us and of the related applications.

Student constructs knowledge with teacher guidance.
Student applies knowledge by the end of the school year.
 
Student reinvests knowledge.
