Question

Need help with the following chemistry problem! 

Suppose you have 1/2 mole of H2S, 3/4 mole of H20, 2 moles of H2, and 1 mole of SO2 which
are allowed to react in a vessel maintained at a temperature of 300 K and a pressure of 10ʻPa.
(a) Write down a balanced chemical reaction, with H2S and H20 as the reactants.
(b) Write down the condition of equilibrium in terms of the chemical potentials.
(c) Show that the number of Hz moles is given by
nH, = 2 – 3A,
where A is the proportionality constant defined in class, and write similar equations for
the other three components. For each component, find the value of A where n; vanishes.
(d) Show that Amax = 2/3 and Amin = -3/8. Which components are depleted in these cases?
(e) Assume the nominal solution of the equilibrium condition gives A = 1/4. What fraction
of each component is in the mixture?
(f) Suppose that we increase the pressure, and this changes the nominal value of A to 0.8.
What fraction of each component is in the mixture now?
