At what temperature will 128 g of `SO_(2)` confined in a vessel of `5 dm^(3)` capacity exhibit a pressure of 10.0 bar? The van der waals constants for `SO_(2)` are a = 6.7 bar `L^(2) mole^(-2)` and b = 0.0564 `L mol^(-1)`.

Explanation

`V=2L,a=3.648L` bar `K^(-1)`
`T=30^(@)C,b=0.0427` L `mol^(-1)`
`m_(CO_(2))=154g`
`therefore` moles of `CO_(2)=(150)/(44)=3.41`
`(P+(n^(2)a)/(V^(2)))(V-nb)=nRT`
`thereforeP=(nRT)/((V-nb))-(an^(2))/(V^(2))=35.73` bar
