Question

The standard potential of electrode isZn+2(0.02M) | Zn (s) is -0.76V. Calculate it’s potential.​

Answer 1

Answer:

The standard electrode potential E^ and its temperature coefficient ( dE^ dT ) for a cell are 2V and - 5 × 10^-4 VK^-1 at 300 K respectively. The cell ...

We have, Δ G = Δ H - Δ S - - - - - - - - - (1)Also, Δ G = - nFEcell = - 2 × 96500 × 2 = - 4 × 96500 Now, Δ S = nF dEdT = 2 × 96500 × ( - 5
