Consider the following cell written in standard notation: Pt, H₂(1 atm)/HCI (1 M, aq) // 1 M KCI (aq) / Ag, AgCl AGP / kJmol-1 AH / kJmol-1 -127.2 -109.6 -167.4 -131.4 AgCl(s) HCI (a = 1) Q 3(a) [25 Marks] Use the data given in the table to calculate the standard cell potential, E°. You should show all relevant equations and units. Comment on the result. Q 3(b) [25 Marks] Including appropriate reaction equations, describe what occurs as the cell reaction proceeds. [50 Marks] Q 3(c) Calculate the temperature coefficient of the cell potential, E/OT, and draw a graph of E vs. T from 10 °C to 35 °C. Comment on the plot and suggest what result would be observed at temperatures above 100 °C.
