Given a mass transfer coefficient k1 of 0.5 and k2 of 1.0, calculate the flux if the bulk concentrations are C1 = 0.2 and C2 = 0.05.
💡 Hint: Examine both concentrations' contributions to total flux.
If a lake has a VOC concentration of 0.3 mg/L and the ambient air shows 0.02 mg/L, apply Henry's law to find the equilibrium concentration.
💡 Hint: The focus is on understanding what values are needed for kH.
