"ELECTROLYTE CONDUCTIVITY DATA: PREDICTOR EQUATION, NONLINEAR LEAST SQUARES FIT. The molar conductivity of an electrolyte such as hydrochloricacid can be predicted as a function of its concentration using the equation: ■ Γ = a0 + a1*c^0.5 ■ Where Γ is the molar conductivity in Ω^-1 cm^2 mol^-1 and c is the electrolyte concentration in mol dm^-3. To obtain the values of the coefficient a0 ( the molar conductivity at zero concentration) and a1, a nonlinear least-squares fit to the experimental data is made. *** Answer(s) to Problem(s) **** (c) Copyright PCSCC, Inc., 1993Data and variable values are already entered. Type S to start fit. Use default value of tolerance, just type (enter). A0=424.6 and A1=-118. Type any key to exit. ||For hydrochloric acid at 298.15K, data in (concentration, molarconductivity) or (c,Γ) pairs are: (0.0005,422.74), (0.001,421.36), (0.005,415. 80), (0.01,412.0), (0.02,407.24), (0.05,399.09). What is the molar conductivity at zero concentration? (from Glasstone, S., Textbook of Physical Chemistry, 2nd ed., Macmillan, London, 1948.) Type comma key to see entire comment.
