Important Equation Formats

This is the third video in the Equations and Solvers Supplement to SCoRE, a Self-Study Course on Reaction Engineering (https://buffalobadger.github.io/SCoRE/). SCoRE is based on the online book, “Reaction Engineering Basics” (https://buffalobadger.github.io/RE_Basics/). When solving ATEs numerically they must be rewritten as equivalent residual expressions. Sets of ODEs must be written as derivative expressions. It is important that you understand what a residual is and that you be able to write ATEs as residual expressions and ODEs as derivative expressions in preparation for solving them numerically. 0:00 Intro 0:46 Writing Residual Expressions 2:34 Derivative Expressions 3:35 Using Linear Algebra to Evaluate Derivatives I hope you found this video to be informative. Take care. Recorded June 2025.
