the concentration of co2 in a soft drink bottle with a partial pressure of co2 of 6.5 atm over the liquid at 29 C is 2.2 x 10^-1 M. The Henry's law constant for CO2 at this temperatur is

Respuesta :

Answer: The Henry's constant for carbon dioxide is [tex]3.38\times 10^{-2}mol/L.atm[/tex]

Explanation:

To calculate the molar solubility, we use the equation given by Henry's law, which is:

[tex]C_{CO_2}=K_H\times p_{CO_2}[/tex]

where,

[tex]K_H[/tex] = Henry's constant = ?

[tex]C_{CO_2}[/tex] = molar solubility of carbon dioxide gas = [tex]2.2\times 10^{-1}mol/L[/tex]

[tex]p_{CO_2}[/tex] = partial pressure of carbon dioxide gas = 6.5 atm

Putting values in above equation, we get:

[tex]2.2\times 10^{-1}mol/L=K_H\times 6.5atm\\\\K_H=\frac{2.2\times 10^{-1}mol/L}{6.5atm}=3.38\times 10^{-2}mol/L.atm[/tex]

Hence, the Henry's constant for carbon dioxide is [tex]3.38\times 10^{-2}mol/L.atm[/tex]
