Question

Consider the reaction A(l) + B(s) ---> C(l) + D(g) where l, s, and g indicate species in the liquid, solid, and gas phases, respectively, and each species appears only in the phase indicated. For this reaction, deltaGrxn = -2.4kJ/mol A at 25 C for all pure components in the states of aggregation indicated above. a.) determine the equilibrium amounts and compositions for substances A and C in this system if the liquid mixture formed is ideal, there is an excess of B present, and the partial pressure of component D is maintained at 0.5bar. b.) repeat the calculation in part (a) if the two components present in the liquid, A and C, form a nonideal mixture described by GexAC = 0.3RTxAxC

Explanation / Answer

We have del G = nRT log [C][D]/[A] this gives [c][d]/[a]=.107 given liquid mixture is ideal so we get [c]= [d] =0.107 moles/L
