Question

The standard potential of the cell formed by combining the Cl 2 /Cl – (aq) half-cell with the standard hydrogen electrode is +1.36V and ∂ E o ∂ T P = - 1.2 × 1 0 - 3 VK -1 . What is the value of Δ S reaction o for reaction H 2 g + Cl 2 g → 2 H aq + + 2 Cl aq -, - 1 × 1 0 - 2 JK -1, 2.3 × 1 0 - 2 JK -1, - 2.3 × 1 0 - 2 JK -1, 1 JK -1
