Chemical Reaction Rates (17.1) Flashcards
- Define chemical reaction rate. - Derive rate expressions from the balanced equation for a given chemical reaction. - Calculate reaction rates from experimental data.
1
Q
Rate of Reaction
A
The speed at which reactants are converting into products.
- Usually measured as a change in concentration per unit of time.
2
Q
Rate of Expression
A
An equation that relates the reaction rate to the concentrations of reactants (and sometimes products), often in the form of a rate law.
3
Q
Average Rate
A
The overall change in concentration of reactants or products over a specific time interval.
Calculated as: Δ[Concentration] / Δt
4
Q
Instantaneous Rate
A
The reaction rate at a specific moment in time.
- typically found by calculating the slope of the concentration vs. time graph at the that point.
5
Q
Initial Rate
A
The reaction rate measured right at the start of the reaction.
- Before any significant changes in reactant concentrations occur.
