A positive overall cell potential indicates that reaction will be spontaneous. There is a connection between the Gibbs free energy change (ΔG) and the overall potential:

ΔG = -nFE

where: n - the number of changed electrons, F - Faraday constant, E - the overall potential.
In order for a process to be spontaneous, the Gibbs free energy change has to be negative, and the above relation indicated that the overall potential has to be positive (since the number of electrons and Faraday constant have positive value).

Consider the reaction H2(g) + I2(g) <---> HI(g) with an equilibrium constant of 46.3 and a reaction quotient of 525. Which

WARRIOR [948]

Answer:

The equilibrium will shift to the left to favor the reactants.

Explanation:

Remember that the reaction quotient (Qc) is derived from initial concentrations of reactants and products. Since Qc is greater than Kc, this means that initial concentrations are heavily impacted by a high product concentration ([HI]). Therefore, the reverse reaction will occur and actually create more reactants again ([H2] and [I2]). Thus, the answer is that the equilibrium will shift to the left side to favor the reactants.
