The initial concentration of reactants in a first order reaction is 0.27 M. The rate constant for the reactio is 0.75 s^-1. What
lawyer [7]

Answer:

Final concentration = 0.019 M

Explanation:

Initial Concentration [A]o = 0.27M

Rate constant, k = 0.75 s^-1

Final concentration [A] = ?

Time, t = 1.5s

The relationship between the variables is given by the equation;

ln[A] = ln[A]o - kt

ln[A] = ln(0.27) - (0.75)(1.5)

ln[A] = - 1.309 - 1.125

ln[A] = - 2.434

[A] = 0.019 M

21-B. Mn was used as an internal standard for measuring Fe by atomic absorption. A standard mixture containing 2.00 mg Mn/mL and
Korvikt [17]

Answer:

0.0693M Fe

Explanation:

It is possible to quantify Fe in a sample using Mn as internal standard using response factor formula:

F = A(analyte)×C(std) / A(std)×C(analyte) <em>(1)</em>

Where A is area of analyte and std, and C is concentration.

Replacing with first values:

F = 1.05×2.00mg/mL / 1.00×2.50mg/mL

<em>F = 0.84</em>

In the unknown solution, concentration of Mn is:

13.5mg/mL × (1.00mL/6.00mL) = <em>2.25 mg Mn/mL</em>

Replacing in (1) with absorbances values and F value:

0.84 = 0.185×2.25mg/mL / 0.128×C(analyte)

C(analyte) = <em>3.87 mg Fe / mL</em>

As molarity is moles of solute (Fe) per liter of solution:

\frac{3.87 mg Fe}{mL} \frac{1g}{1000mg} \frac{1mol}{55.845g} \frac{1000mL}{1L} = <em>0.0693M Fe</em>
