Product description
- Determine the surface excess (kmol/m2) for aqueous solutions of phenol at 20 C based on the given surface tension values:
Phenol concentration, kmol/m3 0.0156 0.0625
Surface tension, N/m 58.2*10-3 43.3*10-3
The surface tension of water at a temperature of 20 C is 72.75 * 10-3 N/m. Calculate the areas occupied by one phenol molecule at various concentrations.
