Question

For the following electrochemical cell at 298 K,

Pt(s) | H₂ (g, 1 bar) | H⁺ (aq, 1 M) || M⁴⁺ (aq), M²⁺ (aq) | Pt(s)

E_cell = 0.092 V when \(\frac{[{M^{2+}(aq)]}}{[M^{4+}(aq)]}\)

Given : \(E^0_{M^{4+}/M^{2+}}\) = 0.151 v ; 2.303 RT/F = 0.059 V

The value of x is 

(A) -2 

(B) -1 

(C) 1 

(D) 2

Answer 1

Correct option is (D) 2
