Answer The ethanol is stabilized by strong intermolecular forces between the molecules.wer:
Explanation:
During the phase change represented by the heat of fusion the temperature does not change. The molecules in the liquid state has a higher degree of freedom but are stabilized by the strong hydrogen bonding requiring a larger into of energy to separate the molecules than the heat of fusion.
Answer:
mole fraction benzene = 0.62
mole fraction toluene = 0.38
Explanation:
Raoults law for ideal solutions tells us that the totoal vapor pressure of the solution will be given by adding the partial pressures of the components of the solution and the partial pressures are simply given by the product of the component in solution times its pure vapor pressure at the temperature given:
<h2>p total = x₁ P⁰₁ + x₂ P⁰₂</h2>
where x1 and x2 for this solution denote the mole fractions of benzene and toluene and p⁰ ₁, p⁰₂ the vapor pressures of benzene and toluene respectively.
Solving the algebraic equation:
75 x₁ + 22 x₂ = 55
75 x₁ + 22 ( 1- x₁) = 55 (since x₁ + x₂ = 1)
75 x₁ + 22 - 22 x₁ = 55
53 x₁ = 33
x₁ = 0.62
x₂ = 1 - 0.62 = 0.38
