The reaction rate is the speed at which reactants are converted into products. It's typically expressed as the change in concentration of a reactant or product per unit time.
For a general reaction: aA + bB → cC + dD
The rate can be expressed as:
Rate = -1/a Δ[A]/Δt = -1/b Δ[B]/Δt = 1/c Δ[C]/Δt = 1/d Δ[D]/Δt
Reaction rates can be determined experimentally by measuring concentrations at different times.
The rate law expresses the reaction rate as a function of reactant concentrations:
Rate = k[A]m[B]n
Where:
- k is the rate constant (depends on temperature)
- m is the order with respect to A
- n is the order with respect to B
- The overall reaction order is m + n
Common reaction orders:
- Zero order: Rate = k (rate is independent of concentration)
- First order: Rate = k[A] (rate is directly proportional to concentration)
- Second order: Rate = k[A]2 or Rate = k[A][B] (rate depends on concentration squared or product of two concentrations)
This calculator provides several tools for analyzing reaction kinetics:
