Chemical Reactions & Catalysis

EK-ES-8

Engineering Performance Matrix

Chemical Reaction & Catalysis is important to engineering literacy as it is the knowledge in which engineering professionals use to analyze and design new products and processes by controlling and using chemical reactions. For example, developing more efficient catalysts can reduce the production of environmentally harmful by-products and can enable enhanced energy efficient production processes. More efficient catalysts can also lower the costs of producing important chemical products.

Performance Goal for High School Learners

I can, when appropriate, draw upon the knowledge of Chemical Reactions & Catalysis content, such as (a) reaction rates, rate constants, and order, (b) conversion, yield, and selectivity, (c) chemical equilibrium and activation energy, and (d) fuels, to analyze the factors influencing the processes of reaction and catalysis with mathematical models to solve problems in a manner that is analytical, predictive, repeatable, and practical.
