For the reaction 2 A(aq) <---> B(aq) + C(aq), the standard
Gibbs free enthalpy change is 1.47 kJ at 25oC. The initial
concentration of A(aq) is 0.567 M, the initial concentration of
B(aq) is 0.303 M, and the initial concentration of C(aq) is 0.219
M. What would be the concentration of A(aq) (in mol/L) once we
attain equilibrium (we are still at 25oC)?

We have a solution that has a concentration of 0.348 M for A(aq) and 0.619 M for B(aq). There are no other solutes initially. The reaction 2 A(aq) + B(aq) <---> 2 C(aq) + D(aq) takes place. At equilibrium, the concentration of C(aq) is 0.142 M. What is the equilibrium constant of this reaction? Please use at least 5 decimal places in calculations.

Question 4: (a) (5 points) For the reaction 2 A(aq) = 2 B(aq) + C(aq), the equilibrium constant is 5.08 at 25.0°C. If the concentrations of B(aq) and C(aq) are each 0.221 M, what concentration of A(aq) is required to have a AG value of -10.0 kJ/mol? (b) (4 points) For the reaction A(g) = B(g) + 2 C(g), we start off with just pure A(g) (there is no B(g) or C(g)). When we reach equilibrium, the partial pressure of...

We have already looked at in lab one mantle sample from
San Carlos in Arizona. This sample might have got you thinking
about what minerals are stable in the higher temperature and
pressure environment of the Earth’s mantle. Among possible mantle
minerals are garnet, spinel, olivine, and pyroxene. With
thermodynamics, as in most chemistry courses, keep track of units,
and make sure you do conversions so that you are dealing with like
units! Also show your work.

1. Carbon monoxide poisoning can happen because carbon monoxide has a higher affinity for hemoglobin than oxygen does. This can be seen by comparing the equilibrium constants for the two reactions Hb(a)+02()Hb02(aq) Hb(a)C(e) HbCO(aq) K 1.9x1012 K 1.1x1014 where Hb is hemoglobin. The actual reactions are more complicated since each hemoglobin can accept up to four oxygen molecules, but we will simplify it for this problem A concentration of about 12,500 parts per million of CO is considered highly lethal....
