Many people with severe mental disorders are members of Medicare/Medicaid, which covers most medications. Some legislative changes to Medicare (Part D) now require some patients to be responsible for a co-pay. Should people diagnosed with severe psychotic disorders, like schizophrenia, be responsible for co-pays for their psychiatric medications? Why or why not? Who, if anyone, should pay?

1) The equilibrium constant, K, for the following reaction is 1.29×10-2 at 600 K.
COCl2(g) <--- ---> CO(g) + Cl2(g)
An equilibrium mixture of the three gases in a 1.00 L flask at
600 K contains 0.206
M COCl2,
5.16×10-2 M CO and
5.16×10-2M
Cl2. What will be the concentrations of
the three gases once equilibrium has been reestablished, if
2.88×10-2 mol of CO(g)
is added to the flask?
| [COCl2] | = | M |
| [CO] | = | M |
| [Cl2] | = | M |
2) The equilibrium constant, K, for the following reaction is 1.80×10-4 at 298 K.
NH4HS(s) <--- ---> NH3(g) + H2S(g)
An equilibrium mixture of the solid and the two gases in a 1.00 L
flask at 298 K
contains 0.315
mol NH4HS,
1.34×10-2 M
NH3 and
1.34×10-2 M
H2S. If the concentration of
H2S(g) is suddenly increased to
2.12×10-2 M, what will be the
concentrations of the two gases once equilibrium has been
reestablished?
| [NH3] | = | M |
| [H2S] | = | M |
