100 moles per minute of an equimolar mixture of methyl ethyl ketone (1) and toluene (2) are flashed from 760 mm Hg to 460 mm Hg at 75 C. You know, experimentally that the infinite dilution activity coefficient of methyl ethyl ketone in toluene is 1.44 at this temperature. Likewise, you know that the experimental value for infinite dilution activity coefficient of toluene in methyl ethyl ketone is 1.33 at this temperature. Solve for the composition and amount of each equilibrium phase if the liquid is treated as modeled by the 2-parameter Margules equation.

The answer is 1.82 j/g°c                  

Sorry i dont understand the question can you rephase it?

Idon't know hope someone you

Given data,temperature, t = 230°c = 503 kconsider the chemical reaction,ch₃oh(l) + 1/2 o₂(g)  → ch₂o(g) + h₂o(l)calculate the enthalpy change for the reaction: δh⁰rxn =  σnδh⁰f(products) -  σmδh⁰f(reactants)substitute the values from the table: δh⁰rxn = { -115.9 + (-285.8)} - {0+(-238.7)}              = -163.0 kjcalculate the entropy change for the reaction.δs⁰rxn = (219 + 70) - (127.2 + 1/2 x 205.2) = 59.2 j/kconsider the expression for free energy: δg⁰rxn =  δh⁰rxn - t  δs⁰rxnsubstitute the values in the above equationδg⁰rxn = -163 x 10³ - (503 x 59.2)              = -192777.6 j              = -192.777 kj
