Answer:
5.88 μM is the concentration of red dye in the sample.
Explanation:
Absorbance is defined s capacity of a substance to absorb a light of a specified wavelength.It is calculated by using Beer-Lambert Law:
A = absorbance
= Molar absorptivity
c = concentration
l = Length of the solution through which light passes
Given, A = 0.468, l = d = 1.00 cm,c = ?
()
5.88 μM is the concentration of red dye in the sample.
Answer : The balanced equations will be:
(a)
(b)
(c)
Explanation :
The general rate of reaction is,
Rate of reaction : It is defined as the change in the concentration of any one of the reactants or products per unit time.
The expression for rate of reaction will be :
From this we conclude that,
In the rate of reaction, A and B are the reactants and C and D are the products.
a, b, c and d are the stoichiometric coefficient of A, B, C and D respectively.
The negative sign along with the reactant terms is used simply to show that the concentration of the reactant is decreasing and positive sign along with the product terms is used simply to show that the concentration of the product is increasing.
Now we have to determine the balanced equations corresponding to the following rate expressions.
(a)
The balanced equations will be:
(b)
The balanced equations will be:
(c)
The balanced equations will be:
