Vinyl chloride (H2C=CHCl), the starting material from which PVC polymer is made, has a Henry’s law constant of 0.091 mol/L-atm at 25 °C. What is the solubility of vinyl chloride in water in mol/L at 25 °C and a partial pressure of 0.75 atm?
Verified step by step guidance1
Identify the given values: Henry's law constant (k_H) is 0.091 mol/L-atm, and the partial pressure (P) of vinyl chloride is 0.75 atm.
Recall Henry's Law, which states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. The formula is: S = k_H * P, where S is the solubility.
Substitute the given values into the Henry's Law equation: S = 0.091 mol/L-atm * 0.75 atm.
Perform the multiplication to find the solubility S in mol/L.
Interpret the result to understand the solubility of vinyl chloride in water under the given conditions.
