=El (0) Write the half-reactions for the cell, and show the standard potential of each half-reaction. Determine the standard cell potential through simple calculation. Write the cell reaction for this cell. (iv) Write the Nernst equation for this cell in terms of molality (b) and the mean activity coefficient (Yu) of HCI. (v) Determine the ionic strength (1) for each molality (b) (and complete the above table). (vi) By employing the Debye-Hückel limiting law (DHLL), determine the mean activity coefficient (Yu) of HCI (and complete the above table). (vii) Write the Nernst equation for this cell only in terms of molality (b), where the mean activity coefficient () of HCl does not feature. (viii) Rearrange the equation in (vii) and make a suitable plot, using the data in the table, to determine the standard cell potential. (ix) Now incorporate the standard cell potential, determined from the linear fit in (viii), into the Nernst equation and determine the mean activity coefficient (yd) of HCl (and complete the above table). (x) Comment on any differences that you might observe between the values obtained for the mean activity coefficient (yd) of HCl in (vi) and (ix). Show all your calculations and derivations, however, for (v), (vi) and (ix) you only have to show one set for each of the calculations. Incorporate the linear fit plot into your document. Incorporate the completed table into your document. Convert the document to a PDF file and upload it into your eFundi Dropbox folder. Apart from other sections in the textbook, paragraph 6D.1 can be consulted for assistance.
