Question

The standard e.m.f. of a galvanic cell involving cell reaction with n = 2 is found to be 0.295 V

Answer 1

Answer:

For a cell reaction involving a two-electron change, the standard e.m.f. of the cell is found to be 0.295V at 25°C. The equilibrium constant of the reaction at 25°C would be 1 × 1010 . E°cell = 0.0591/n * logKc. Or, 0.295 = 0.0591/2 * logKc or, 0.295 = 0.0295 logKc or, Kc = antilog 10 or, Kc = 1 × 1010.

Answer 2

$\large \tt kc \: = 1 \times {10}^{10}$
