The methods of this section can also be applied to reactions in which one set of solids converts to another. A geologically important example is the transformation of albite into jadeite + quartz:
Use the data at the back of this book to determine the temperatures and pressures under which a combination of jadeite and quartz is more stable than albite. Sketch the phase diagram of this system. For simplicity, neglect the temperate and pressure dependence of both

- Use the ideal gas law, “PV-nRT”, and the universal gas constant R = 0.0821 L*atm to solve the following problems: K*mol If pressure is needed in kPa then convert by multiplying by 101.3kPa / 1atm to get R =8.31 kPa*L / (K*mole). Show your answers legibly, concisely, and completely. Use separate sheet of paper. If I have 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 liters, what is the temperature?arrow_forwardThe porous catalyst pellet shown in Figure 1 has an overall radius R and a thermal conductivity k (which may be assumed constant). Because of the chemical reaction occurring within the porous pellet, heat is generated at a constant rate of Se cal/em s. Heat is lost at the outer surface of the pellet to a gas stream at a constant temperature T, by convective heat transfer coefficient h. Gas bemperature T, Figure I.
