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.

For #10-M 3: Consider the gas phase equilibrium, 2 NO2(g)+ 40(g) N20s(g). The enthalpy change for this reaction is -170 kJ and the equilibrium constant is 2.5 at 150 °C. 10. For the above reaction, if N2(g) is added at a constant total pressure of 5 bar, (A) the equilibrium will move to the left and K will decrease the equilibrium will move...

1. An existing absorption tower contains the equivalent of 3.0 theoretical trays and is being used to absorb SO2 from air by pure water at 293 K and 1.0 atm. The entering gas contains 15 mol % SO2 and the inlet air flow rate is 150 kg inert air/h-m2. The entering water rate is 6000 kg inert air/h m2. Calculate the composition of the outlet gas. (Hint:...
