Problem 5.28. Calcium carbonate, CaCO3, has two common crystae forms, calcite and aragonite. Thermodynamic data for these phases can be found at the back of this book (a) Which is stable at earth's surface, calcite or aragonite? (b) Calculate the pressure (still at room temperature) at which the other phase should become stable. All of the values in this table are for one mole of material at 298 K and 1 bar. Following the chemical formula is the form of...
I wasn't given the partial pressures so why do you need it? can the problem really not be solved without it? 1 bar for each 4. (11.11) The combustion of hydrogen is a reaction that is known to "go to completion." a. Use data in Appendix H to evaluate the thermodynamic equilibrium constant at 298.15 K for the reaction H2(g) + {O2(g) → H2O(1) b. Assume that the reaction is at equilibrium at 298.15 K in a system in which...
