Title: WebStraw: Chemistry Review Anki Deck / Equilibrium / 6. Reaction Rates

Q: Reaction Rate
A: Change in concentration of a reactant/product of a chemical reaction per unit time.

Q: Average Rate of Change:
A: The change in reactant/product concentration over a give time interval.

Q: Formula for the Average Rate of Change
[...]
 [A]: concentration of A in mol/L
Δ[A]: change in concentration of A in mol/L
A: reactant/product
A: Δ[A]/Δt

Factors Affecting Reaction Rates
1. Surface Area
2.  Temperature of Reaction System
3. Prescence of Catalyst
4. Concentration of Reactants
5. Chemical Nature of Reactants

Q: Catalyst, in chemistry, any substance that [...] without itself being consumed.
A: increases the rate of a reaction

Q: Catalyst [...]  activation energy, but does not change the energies of the original reactants or products.
Therefore catalysts [...] change equilibrium.
A: lowers; DO NOT

Q: The minimum energy necessary to form a product during a collision between reactants is called the [...]
A: activation energy (E_a)

Q: Collision Theory → reactions can only occur if:
1. There is a [...] between molecules
2. Molecules collide in the [...]
3. [...] to break chemical bonds holding the molecules together (E_a)
A: collision; correct orientation; Enough energy is provided
