WebTranscribed Image Text: Henry's Law: Henry's Law constant for trichloroethylene (TCE) at 25°C in equilibrium with water is 1.03 L atm mol-1. The concentration of TCE in a lake is 1 µmol/L. What is the concentration of TCE (in ppm,) at the surface of the lake? WebFigure 13.3.1 shows a system at equilibrium (a) where the rate across the suface/vapor boundary is constant (red arrows equal black arrows). In (b) the pressure is increased (by decreasing the volume). This increases the concentration in the vapor phase, and so the collision frequency with the liquid increases, causing more to be dissolved.

WebHenry's law constants were obtained simultaneously over the 25° C to 45° C temperature range, providing data on H beyond the cur-rently available data (up to 35° C).
