2. For aqueous solutions of sodium dodecyl sulfate, the logarithms of the CMC were determined at two temperatures. Determine how increasing temperature affects the surface activity of sodium dodecyl sulfate. logKKM=-2.04 (at 20 C) and logKKM=-2.01 at 60 C; bkkm=44 mJ/m2 at 20 C, bkkm=41 mJ/m2 at 60 C, b0=72.72 mJ/m2 at 20 C; b0=66.18 mJ/m2 at 60 C; concentration in mol/l.
