Consider an electrochemical cell: A(s) | A n+ (aq, 2 M) || B 2n+ (aq, 1 M) B(s). The value of 
for the cell reaction is twice that of 
at 300 K. If the emf of the cell is zero, the 
(in J K -1 mol -1 ) of the cell reaction per mole of B formed at 300 K is____.
(Given: ln(2) = 0.7, R (universal gas constant) = 8.3 J K -1 mol -1 . H, S and G are enthalpy, entropy and Gibbs energy, respectively.)
