question

For the reaction Cd(Hg) + Hg_2SO_4(s) + (8/3)H_2O \rightleftarrows CdSO_4 \bullet (8/3)H_2O(s) + 3Hg(l) the voltage as a function of temperature is given by \epsilon = 1.01845 - (4.1 × 10^-5)(\texttheta - 20) - (9.5 × 10^-7)(\texttheta - 20)^2 where \texttheta is the temperature in °C. Calculate the value of \DeltaS at 25°C given that one mole of CdSO_4. (8/3) H_2O is formed and \DeltaS =nF(d\epsilon/dT) wheren = 2 andF = 9.648456 × 10^4 C mol^-1
