Answer:

A. Aspartic acid is unstable at temperatures below 150°C.

Explanation:

Aspartic acid  is an amino acid that is used in the production of proteins within  living cells.  It contains an amino group and a carboxylic acid, and can be synthesized by the body. It is a non-essential amino acid. The prebiological formation of aspartic acid occured at a certain temperature range. It was deduced from the passage that aspartic acid is unstable at temperatures below 150°C. The transamination of oxaloacetate in the human body gives rise to the formation of aspartate which is facilitated by the enzyme, aminotransferases. Aspartate also play a major role in the formation of urea by acting as a metabolite.

What is ΔG° at 298 K for the following equilibrium? Ag+(aq) + 2NH3(aq) Ag(NH3)2+(aq); Kf = 1.7 × 107 at 298 K a. 41 kJ b. 0 c. –
jekas [21]

Answer:

ΔG° = 41.248 KJ/mol (298 K); the correct answer is a) 41 KJ

Explanation:

Ag+(aq)  +  2NH3(aq)  ↔ Ag(NH3)2+(aq)

⇒ Kf = 1.7 E7; T =298K  

⇒ ΔG° = - RT Ln Kf.....for aqueous solutions

∴ R = 8.314 J/mol.K

⇒ ΔG° = - ( 8.314 J/mol.K ) * ( 278 K ) ln ( 1.7 E7 )

⇒ ΔG° = 41248.41 J/mol * ( KJ / 1000J )

⇒ ΔG° = 41.248 KJ/mol
