Answer:

The reaction is spontaneous.

Explanation:

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).

What is the equilibrium constant, KC if the reaction is a gas phase reaction? (Ans.: Gas: KC = 0.328 dm3/mol)
valentina_108 [34]

Answer:

Equilibrium constant Kc = Qc = quotient of reactant(s) and product(s)

Kc = [C]x[D]y..../[A]m[B]n..... = 0.328dm3/mol, where [C]x[D]y is the product and [A]m[B]n is the reactant(Both in gaseous states)

Explanation:

When a mixture of reactants and products of a reaction reaches equilibrium at a given temperature, its reaction quotient always has the same value. This value is called the equilibrium constant (K) of the reaction at that temperature. As for the reaction quotient, when evaluated in terms of concentrations, it is noted as Kc.

That a reaction quotient always assumes the same value at equilibrium can be expressed as:

Qc (at equilibrium) = Kc =[C]x[D]y…/[A]m[B]n…

This equation is a mathematical statement of the law of mass action: When a reaction has attained equilibrium at a given temperature, the reaction quotient for the reaction always has the same value.
