(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 chemical reaction is an equation that indicates the relationship between reaction rate and concentrations or pressures of the reactants and other constant parameters. For zero-order reactions, the reaction rate is independent of the concentration of a reactant. A first order reaction depends on the concentration of only one reactant. The rate of a second-order reaction may be proportional to one concentration squared.

Interpretation Introduction
(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 chemical reaction is an equation that indicates the relationship between reaction rate and concentrations or pressures of the reactants and other constant parameters. For zero-order reactions, the reaction rate is independent of the concentration of a reactant. A first order reaction depends on the concentration of only one reactant. The rate of a second-order reaction may be proportional to one concentration squared.
Interpretation Introduction
(b)
Interpretation:
The rate constant of reaction should be determined.
Concept introduction:
For second order reaction:
1[A]t−1[A]0=kt
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.
Interpretation Introduction
(c)
Interpretation:
Time at which [ArSO2H] is equal to 0.05 M should be determined.
Concept introduction:
In a second order reaction, the rate is linearly proportional to the concentration squared of the reactant.
Interpretation Introduction
(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.
Interpretation Introduction
(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.

A chemist titrates 120.0 mL of a 0.7191M dimethylamine ((CH3)2NH) solution with 0.5501 M HBr solution at 25 °C. Calculate the pH at equivalence. The
pk of dimethylamine is 3.27.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of HBr solution added.

Alcohols can be synthesized using an acid-catalyzed hydration of an alkene. An alkene is combined with aqueous acid (e.. sulfuric acid in water). The
reaction mechanism typically involves a carbocation intermediate.
