Q112
For the following reactions, the standard free energy change is given at 1773 K as follows: 2/3 Cr2O2(s) = 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 PH_2PH_0 ratio that has to be maintained at the exit of the reactor is
For the following reactions, the standard free energy change is given at 1773 K as follows:
Cr2O2(s) = 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 ratio that has to be maintained at the exit of the reactor is
Cr2O2(s) = 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 ratio that has to be maintained at the exit of the reactor is
