Question

The standard emf of a cell, involving one electron change is
found to be 0.591 V at 25°C. The equilibrium constant of the
reaction is (F = 96500 C mol⁻¹)
(a) 1.0 × 10¹ (b) 1.0 × 10⁵
(c) 1.0 × 10¹⁰ (d) 1.0 ×10³⁰

Answer 1

Explanation:

hope it helps u.........

Answer 2

The equilibrium constant of the reaction is 1×10¹⁰

- = 0.591 V

- T = 25°C = 25 + 273  K = 298 K

- F = 96500 C mol⁻¹

- n = 1

- R = 8.314 J/K

- using formula : = (2.303 RT/nF) × log

                    log = nF/ 2.303 RT

                                = (1 × 96500 × 0.591)/ (2.303 × 8.314 × 298)

                     log = 10

                            =

- So the correct answer is option (c) 1.0 × 10¹⁰
