Chemical and Phase Equilibrium

Phase diagrams or equilibrium phase diagrams are the graphical representations that show the phase transformations of the constituting elements with respect to the pressure, temperature, and compositions. The diagrams show the conditions that limit the different phases, namely solid, liquid, and gas. The diagram can also be utilized to verify the relations between the state variables. Most of the phase diagrams are temperature-pressure phase diagrams, with the variable parameter as the composition. Usually other variables such as solubility and pressure parameters are not indicated in the phase diagram. For a one-component system (unary phase diagram), the phase diagram is generally a function of temperature and pressure as the state variables, or temperature and volume. However, for a binary system (two-phase) having two components, the phase diagram is a function of temperature and composition as the state variables only. Coexisting of the different phases of the constituting elements is indicated in the phase diagram. A ternary phase diagram can be characterized by consisting of three phases in equilibrium.

RP-1 is highly refined form of kerosene used for many first stage rocket engines. The average composition of it is indicated by CH1.9 a. What is the stoichiometric mixture ratio (MR) for RP-1 and oxygen? b. Now, you have a mixture of air and RP-1 with three times more air (in terms of moles) than is needed to burn all the fuel. How high is the final temperature? The heats of formation are given in the table below. In molar quantities, assume 1 mole of air is (O2+3.76N2). The reactants have a temperature of 25°C before combustion. You may use the average values of the specific heats for each constituent. C.
