A sample containing 3.25 moles of He (1 bar, 350 K) is mixed with 2.25 moles of Ne (1 bar, 350 K) and 1.75 moles of Ar (1 bar, 350 K). Calculate ΔmixG and ΔmixS.
Added by Kathryn W.
Step 1
Mole fraction of He: $$x_{He} = \frac{3.25}{3.25 + 2.25 + 1.75} = \frac{3.25}{7.25}$$ Mole fraction of Ne: $$x_{Ne} = \frac{2.25}{7.25}$$ Mole fraction of Ar: $$x_{Ar} = \frac{1.75}{7.25}$$ Now, we can calculate the change in Gibbs free energy for the mixing Show more…

A mixture of Ne and $\mathrm{Ar}$ at $250 \mathrm{~K}$ has a total $\mathrm{K}: \mathrm{E} .=3 \mathrm{~kJ}$ in a closed vessel, the total mass of Ne and Ar is $30 \mathrm{~g}$. Find mass $\%$ of Ne in gaseous mixture at $250 \mathrm{~K}$. (a) $61.63$ (b) $38.37$ (c) $50 \%$ (d) $28.3$
A 3.50 mol sample of an ideal gas with Cv,m = 3R/2 is expanded adiabatically against a constant external pressure of 1.45 bar. The initial temperature and pressure are Ti = 310 K and Pi = 15.2 bar. The final pressure is Pf = 1.45 bar. Calculate q, w, ∆U, and ∆H for the process. Answers: (q = 0, ∆U = w = -4.90 kJ, ∆H = -8.16 kJ, Tf = 198 K)
