The equilibrium constant for the gas phase reaction
stellarik [79]
The equilibrium constant is found by [product]/[reactant]

If the equilibrium constant is very small, such as 4.20 * 10^-31, then that means at equilibrium there is very little product and a lot of reactant.
And likewise, if there is a lot of product formed, and very little reactant, then the K value will be very large, which tells us that it is predominantly product.

At equilibrium, for any reaction, there will always be some reactant and some product present. There cannot be zero reactant or zero product. Also keep in mind that the equilibrium constant is dependent on temperature.

At equilibrium, for your reaction, it is predominantly reactants.

A specific steroid has a λmax of 257 nm and a molar absorptivity ε of 11 , 500 L mol − 1 cm − 1 . What is the concentration of t
joja [24]

Answer:

7.83\times 10^{-6} M is the concentration of the compound in a solution.

Explanation:

Using Beer-Lambert's law :

Formula used :

A=\epsilon \times C\times l

Where:

A = absorbance of solution

C = concentration of solution

l = path length

\epsilon = molar absorptivity coefficient

We have:

C = ? , l = 1.00 cm, A = 0.090

\epsilon = 11,500 L/(mol cm)

C=\frac{A}{\epsilon l}=\frac{0.090}{11,500 L/(mol cm)\times 1.00 cm}

C=7.83\times 10^{-6} M

7.83\times 10^{-6} M is the concentration of the compound in a solution.
