1. Calculate H o for the process Hg 2 Cl 2 (s) 2Hg (l) + Cl 2 (g) from the following information Hg (l) +
1.
Calculate Ho for the process Hg2Cl2(s) 2Hg(l) + Cl2(g)
from the following information
Hg(l) + Cl2(g) HgCl2(s) | Ho = -187.0 kJ/mol |
Hg(l) + HgCl2(s) Hg2Cl2(s) | Ho = -640.0 kJ/mol |
2.
Calculate Ho for the process Co3O4(s) 3 Co(s) + 2 O2(g)
from the following information
Co(s) + O2(g) CoO(s) | Ho = -157.5 kJ/mol |
3 CoO(s) + O2(g) Co3O4(s) | Ho = -743.9 kJ/mol |
3.
