Diffusion Rate Calculator
Fick’s First Law • Calculates Flux (J) and Rate (R) + optional trend graph
Fick’s Law
Scientific notation supported (example: 1e-9).
Used for Rate: R = J × A.
C₁ and C₂ share the same units.
ΔC = C₁ − C₂.
Must be non-zero.
Flux: mol/m²·s • Rate: mol/s
Enter values and click Calculate.
Trend Graph (useful for learning)
Plots how Flux/Rate change as thickness (Δx) changes, using your current D, A, C₁, C₂.
Tip: Thickness in the graph uses the same unit selector as Δx above.
