Question
Chapter 23, Problem 32QAP
Interpretation Introduction
Interpretation:
The completed amino acids sequence needs to be determined according to the given information.
Concept introduction:
Amino acids are organic compounds containing amino as well as acidic groups. The general molecular formula of an amino acid is as follows:
Here, R refers to different group for different amino acids. If there is more than one amino group present in an amino acid, they are considered as basic amino acids and if there is more than one carboxylic group then, they are considered as acidic amino acids.
Amino acids are the simplest unit of a peptide chain. These amino acids are linked through peptide bonds and results in the formation of protein.

a.
Based on the above data what is the rate law expression?
b. Solve for the value of k (make sure to include proper units)
2. The proposed reaction mechanism is as follows:
i.
ii.
BrО¸¯ (aq) + H+ (aq) → HBrO3 (aq)
HBrO³ (aq) + H* (aq) → H₂BrO3* (aq)
iii.
H₂BrO³* (aq) + Br¯ (aq) → Br₂O₂ (aq) + H2O (l)
[Fast]
[Medium]
[Slow]
iv.
Br₂O₂ (aq) + 4H*(aq) + 4Br(aq) → 3Br₂ (l) + H2O (l)
[Fast]
