Calculate the rate of diffusion for a substance given its concentration gradient of 5 mol/m³ over a distance of 2 meters, using a diffusion coefficient of 0.1 m²/s.
💡 Hint: Remember the negative sign indicates direction.
A river has been found contaminated by a pollutant with mass transfer into water from sediment influenced by a concentration gradient of 3 mmol/L. If the sediment concentration is 12 mmol/L, how would you set up your mass balance equation?
💡 Hint: Think what trends in concentrations might affect your calculations.
