Problem 3.33 Consider the reaction 2HI = H2 +12 which occurs in the gas phase. Start initially with 2 mol of HI and 0 mol each of H, and 12. Assume that the reaction occurs at temperature T and pressure P. Use ideal gas equations for the chemical potential. (a) Compute and plot the Gibbs free energy, G(T, P, E), as a function of the degree of reaction, &, for (i) P= 1 atm and T = 298 K and (ii) P=1 atm and T = 596 K. (b) Compute and plot the affinity, ACT, P, X), as a function of the degree of reaction, &, for (i) P=1 atm and T = 298 K and (ii) P= 1 atm and T = 596 K. (c) What is the degree of reaction, &, at chemical equilibrium for P = 1 atm and temperature T = 298 K? How many moles of HI, H2, and I, are present at equilibrium? (d) If initially the volume is Vo, what is the volume at equilibrium for P= 1 atm and T = 298 K? (e) What is the heat of reaction for P = 1 atm and T = 298 K? = =
