Challenge Problems
Push your limits with advanced challenges
You need to analyze the evaporation rates of two chemicals, ethylene glycol (molecular weight 62) and benzene (molecular weight 78). Compare their evaporation tendencies considering molecular weight and suggest appropriate correlations.
💡 Hint: Consider how the relative weights function in terms of volatility.
In a scenario where a dense non-aqueous phase liquid is introduced into a shallow river, discuss how one would calculate the mass transfer coefficient and the implications of molecular weight difference.
💡 Hint: Think about how the environmental context changes based on the chemical properties.
