Calculate the standard cell potential at 25 ∘c for the reactionx(s)+2y+(aq)→x2+(aq)+2y(s)w here δh∘ = -829 kj and δs∘ = -367 j/k

The standard cell potential at 25 ∘C for the reaction is 2.72 Volts.

Explanation:

Δ°G = Δ°H - TΔ°S (Gibb's equation)

Δ°G =  Gibbs free energy

Δ°H = Enthalpy of the reaction at temperature T

Δ°S = Entropy of the reaction at temperature T

n = number of electrons transferred

F = Faraday's constant = 96500 C

= standard electrode potential of the cell

We have:

Δ°H = -829 kJ = -829000 J

Δ°S = -367 J/K

T = 25 C = 298.15 K

n = 2

The standard cell potential at 25 ∘C for the reaction is 2.72 Volts.

answerleaving cheese out to get moldy;

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
