⚗️Reaction Rate Calculator
Reaction rate measures how quickly reactants are converted to products over time: rate = −Δ[Reactant]/Δt = +Δ[Product]/Δt. Factors affecting rate include concentration, temperature, catalysts, surface area, and state of reactants.
- 1Rate = Δ[concentration] / Δtime
- 2Rate law: rate = k[A]^m[B]^n (m,n are reaction orders)
- 3Rate constant k increases with temperature (Arrhenius)
- 4Doubling temperature roughly doubles reaction rate for each 10°C increase (rule of thumb)
[A] drops from 0.5M to 0.3M in 20 seconds=Rate = 0.2M/20s = 0.01 mol/L/s−Δ[A]/Δt = 0.2/20

Fun Fact
The "10°C rule" (Q10) states that reaction rate approximately doubles for every 10°C temperature increase. This is why food spoils much faster at room temperature than in a refrigerator.
