Configurational entropy due to ideal mixing in a binary A - B system is expressed as:
ΔSmix = - R(XA In XA + XB In XB),
where XA and XB are mole fractions of A and B respectively.
ΔSmix is maximum at XA = . . . . . . . .
For the following reactions, the standard free energy change is given at 1773 K as follows:
$$\frac{2}{3}$$ Cr2O2(s) = $$\frac{4}{3}$$ Cr(s) + O2(g)
ΔG° = 447800 J
2H2(g) + O2(g) = 2H2O(g)
ΔG° = - 297000 J
If chromium oxide powder has to be reduced by hydrogen in a fludised bed, the minimum $$\frac{{P{H_2}}}{{P{H_0}}}$$ ratio that has to be maintained at the exit of the reactor is
Consider the equilibrium A(g) + B(g) = AB(g). When the partial pressure of A is 10-2 atm; the partial pressure of B is 10-3 atm and the partial pressure of AB is 1 atm; the equilibrium constant K is
For any given partial pressure of CO over liquid steel at a constant temperature, the activities of carbon and oxygen in the metal are related to a constant β as
