Henry's law constant for co2

Web4 apr. 2024 · > Henry's law is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. The proportionality factor is called Henry's law constant ${{K}_{H}}$. Given, Henry’s law constant (${{K}_{H}}$ ) = $1.67\times {{10}^{8}}Pa$ So, for carbon dioxide gas, we can write that WebThe short answer is no. The long answer is: Henry's law works for small concentrations of ideal mixtures at equilibrium. Henry's Law constant varies with temperature according to the Van't Hoff equation: k ( T) = k ( T ∘) e x p [ − C ( 1 T − 1 T ∘)] Here C is a constant related to the enthalpy of solvation for each gas, and ∘ ...
