Section 7 1 4 presents calculations for applying Raoult’s Law to calculate the contribution of individual chemical species to the total emissions Section 7 1 5 presents worked examples with estimated emissions shown to two significant figures This level of precision is chosen arbitrarily and may overstate the accuracy of the loss estimates
Raoult’s law is valid for similar substances – this is because then interactions with other substance will closely mimic those with the pure substance We can use Raoult’s law to write the equation for the chemical potential of the liquid A: µ (l )=µ A(l)+RTlnX This equation is valid only for ideal solutions (similar interactions ?mixH = 0)
