Concept explainers
(a)
Interpretation:
The given reaction is to be shown as second order using the given data.
Concept introduction:
The rate law/rate equation for a
(b)
Interpretation:
The rate constant of reaction should be determined.
Concept introduction:
For second order reaction:
Where, k is rate constant, t is time, [A]t is concentration of A at time t and [A]o is the concentration of A at initial time that is at t = 0.
(c)
Interpretation:
Time at which [ArSO2H] is equal to 0.05 M should be determined.
Concept introduction:
In a second order
(d)
Interpretation:
Time at which [ArSO2H] is equal to 0.025 M should be determined.
Concept introduction:
In a second order reaction, the rate is linearly proportional to the concentration squared of the reactant.
(e)
Interpretation:
Time at which [ArSO2H] is equal to 0.035 M should be determined.
Concept introduction:
In a second order reaction, the rate is linearly proportional to the concentration squared of the reactant.

- 4. Refer to the data below to answer the following questions: The octapeptide saralasin is a specific antagonist of angiotensin II. A derivative of saralasin is used therapeutically as an antihypertensive. Amino acid analysis of saralasin show the presence of the following amino acids: Ala, Arg, His, Pro, Sar, Tyr, Val, Val A.Sar is the abbreviation for sarcosine, N-methyl aminoethanoic acid. Draw the structure of sarcosine. B. N-Terminal analysis by the Edman method shows saralasin contains sarcosine at the N-terminus. Partial hydrolysis of saralasin with dilute hydrochloric acid yields the following fragments: Tyr-Val-His Sar-Arg-Val His-Pro-Ala Val-Tyr-Val Arg-Val-Tyr What is the structure of saralasin?arrow_forwardWhat is the structure of the DNA backbone?arrow_forwardPLEASE PLEASE PLEASE use hand drawn structures when possarrow_forward
