The Value of the Equilibrium Constant for the Following Reaction

question 23

Multiple Choice

The value of the equilibrium constant for the following reaction is 0.200 at a given temperature: 2HI(g) ⇌ H₂(g) + I₂(g) If [HI] = 0.200 M, [H₂] = 0.200 M, and [I₂] = 0.200 M, determine if the reaction is at equilibrium. If it is not, in which direction will it proceed to reach equilibrium?

• A)The reaction is at equilibrium.
• B)The reaction is not at equilibrium, it will shift to the left.
• C)The reaction is not at equilibrium, it will shift to the right.
• D)It is not possible to tell if the reaction is at equilibrium.
• E)To reach equilibrium, the value of K_eq must change.

Definitions:

Protein

Macromolecules consisting of long sequences of α-amino acids [H2N-CHR-COOH] in peptide (amide) linkage (elimination of H2O between the α-NH2 and α-COOH of successive residues). Protein is three-fourths of the dry weight of most cell matter and is involved in structures, hormones, enzymes, muscle contraction, immunologic response, and essential life functions. The amino acids involved are generally the 20 α-amino acids (glycine, l-alanine) recognized by the genetic code. Cross-links yielding globular forms of protein are often effected through the 2SH groups of two sulfur-containing l-cysteinyl residues, as well as by noncovalent forces (such as hydrogen bonds, lipophilic attractions).

Carbohydrate Reserves

Stored sugars and starches in the body, primarily in the liver and muscles, used as a source of energy.

Protein

Essential macromolecules composed of amino acids, crucial for the structure, function, and regulation of the body's cells, tissues, and organs.

Dairy Products

Food products made from milk, such as cheese, butter, yoghurt, and ice cream.
