The standard voltage of the cell Ag(s)$\mid$AgBr(s)$\mid$Br ^- (aq)m Ag⁺(aq)$\mid$Ag(s) Is +0.73 V at 25$\degree$C.Calculate the equilibrium constant for the cell reaction.

Question

Quizplus · Accepted Answer

The equilibrium constant (K) for the cell reaction can be calculated using the equation:

K = exp(-nF(Ecell/RT))

Where n is the number of electrons transferred in the reaction (2 in this case), F is the Faraday constant, R is the gas constant, and T is the temperature in Kelvin.

Substituting the given values, we get:

K = exp(-2*96500*(0.73)/(8.314*298)) = 2.2 x 10^-12

The closest answer choice is C.
