Problem 19.58 A certain reaction has delta H degree = + 35.3kJ and delta S degree = 85.9J /K. Part C Calculate delta G degree for the reaction at 298 K.Problem 20.102 A voltaic cell is constructed from an Ni2+ (aq)-Ni(s) half-cell and an Ag(aq)-Ag(s) half-cell. The initial concentration of Ni2+ (aq) in the Ni2+ -Ni half-cell is [Ni2+] = 1.60 x 10^-2M . The initial cell voltage is +1.12V. will increase will decrease Part C What is the initial concentration of Ag (aq) in the Ag+ -Ag half-cell? Express your answer using one significant figure. [Ag+ (aq)]1= 0.9 Part B Calculate the standard cell potential (E degree ) for the reaction X(s) + Y+ (aq)X+ (aq) + Y(s) ?f K = 8.70x10^-3. Express your answer numerically in volts.
