The release of volatile organic compounds into the atmosphere is regulated to limit ozone formation. In a laboratory simulation, 5% of the ethanol in a liquid detergent is released. Thus, a "down-the-drain" factor of 0.05 is used to estimate ethanol emissions from the detergent. The kH values for ethanol and 2-butoxyethanol (C₄H₉OCH₂CH₂OH) are 5x10⁻⁶ atm . m3/mol and 1.6x10⁻⁶ atm . m³/mol, respectively. (a) Estimate a "down-the- drain" factor for 2-butoxyethanol in the detergent.

Respuesta :

What are  volatile organic compounds ?

Organic substances known as volatile organic compounds (VOCs) have a high vapour pressure at normal temperature. Low boiling point and high vapor pressure are related to volatility, which is the proportion of the sample's molecules in the surrounding air.

(a)

Realizing that the ratio of the two compounds' kH values actually equals the ratio of their respective "down-the-drain" factors is the simplest way to determine the "down-the-drain" factor for 2-butoxyethanol in water.

(b)(c)

5 x 10^-6 atm m^3 mol^-1 = 5 x 10^-6 x 10^3 dm^3 m^-3 = 5 x 10^-3 L atm mol ^-1

5 x 10^-6 atm m^3 mol^-1 = 5 x 10^-6 x 101325 Pa m^3 mol^-1
