Answer:

The correct answer is oxidation-reduction.

Explanation:

This reduction-oxidation reaction is given by the following semi-reactions:

Br_{2} + 2 e^{-} → 2 Br^{-1} (reduction)

2 K^{0} - 2 e^{-} → 2 K^{1} (oxidation)

Br_{2} is an oxidation agent, K is a reducing agent.  

This means that Br_{2} oxidizes K by increasing its oxidation number from 0 to 1.

Br_{2} is reduced, decreasing its oxidation number from 0 to -1.

Have a nice day!

lana [24]

Answer:

the equilibrium constant is 1.8 x 10⁻5 and strongly favor the reactants.

Explanation:

the chemical reaction provided for the two equation are the same but different direction i.e a reversible reaction. Assuming, the mass of reactants and product and temperature remain constant.

therefore, the equilibrium constant K, is 1.8 x 10⁻5. this is a very small value of K, thereby strongly favor the backward direction to form reactant.
