Formulas and Key Relations
Rate of Chemical Reactions
Average rate = Δc/Δt, measured over a time interval
Instantaneous rate = dc/dt, measured at a specific instant using tangent to concentration-time curve
Key relations
For first-order reactions
k = (2.303/t)log([A]₀/[A]t) and [A]t = [A]₀e⁻ᵏᵗ.
For zero-order reactions
[A]t = [A]₀ - kt.
For first-order
t₁/₂ = 0.693/k (independent of initial concentration).
