30. Solving a chemistry problem

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.
