CHEM 102: General Chemistry II Week 4 Spencer Kociba Drexel University Lecture 9​ (01/30/2017) ● rate= concentration change over time ○ units=amount/time ○ Defined −ither in terms of the reactants or products ○ Ex. Δ[ClO where [ ] indicates concentration Δt ○ Rate= - slope of the instantaneous rate (the slope of the tangent line) ○ Reactants’ concentration over time ■ ■ Rate is negative (with positive Δt) ○ Products’ concentration over time ■ ■ Rate is positive (with positive Δt ) ○ Rates are related to stoichiome
