A student carried out an experiment in which the conductivity of a solution was measured as a function of surfactant concentration in water at 298K. The following plot was obtained. The equation (of the form y=mx+c ) of the two lines in plot were determined to be Line 1: y=6.02343x+0.00142 Line 2: y=1.52184x+0.02508 From additional experiments it was found that for this surfactant H=1.8kJmol1 at 298K. Determine the value of S (in unit of J mol1K1). [ Note: G=+RTlnxm] Do not include your units in the answers otherwise it will be marked incorrect. QUESTION 6 At 298K the CMC of a surfactant in water is 0.0125M. If H, at the CMC, was determined to be 1.06kJ/mol, evaluate G and S. Note: G=+RTlnxm;G=HTS G=20.8kJ/mol;S=+58.9J(molK) G=12.5kJ/mol;S=+120.6J(molK) G=20.8kJ/mol;S=+68.3J(molK) G=10.8kJ/mol;S=+32.8kJ(molK)
