Consider an electrochemical cell: `A(s) | A^(n+) (aq, 2 M) || B2^(n+) (aq, 1 M) | B(s)`. The value of `triangle G^(theta)` for the cell reaction is twice that of `triangle G^(theta)`  at 300 K. If the emf of the cell is zero, the `triangle G^(theta) in J K−1 mol^(−1)` of the cell reaction per mole of B formed at 300 K is ____. (Given: ln(2) = 0.7,  (universal gas constant) `= 8.3 J K−1 mol^(−1)`. H, S and G are enthalpy, entropy and Gibbs energy, respectively.)
