What to Focus On
- Rate = Change in concentration / Time
- Units: mol L⁻¹ s⁻¹
- Rate is expressed with stoichiometric coefficients to make it consistent for all species
- Average rate is over a time interval
- Instantaneous rate is at a specific time
- Instantaneous rate is the slope of the tangent to the concentration-time curve
- Rate increases with concentration and temperature
- Catalyst lowers activation energy
- Physical state and surface area also affect rate
Common Mistakes to Avoid
The order of a reaction is always equal to the stoichiometric coefficients in the balanced equation.
Rate constant (k) changes when concentration of reactants changes.
Half-life of a reaction is always the time taken for concentration to become half, so it depends on initial concentration.
Memory Tips
Rate of Reaction = Change in concentration / Time
Average Rate vs Instantaneous Rate
Rate = -1/2 Δ[NO]/Δt = -Δ[Br₂]/Δt = +1/2 Δ[NOBr]/Δt
Rate Law: Rate = k[A]^x[B]^y
