The gases are mixS for this process as a function of the mole fraction of the first gas, A. Please label your axes. 0.693 Δ S 10 (2) (2 points) Make a plot depicting how the chemical potential, l, of a pure substance, A, varies with temperature in the liquid phase. On the same plot show how the chemical potential, s, varies with temperature in the solid phase for A. Mark the fusion (melting) temperature on this graph. highpressure melting point liquid µ solid Yessore I TI (3) (1 point) How many degrees of freedom are there when moving along the liquid/solid boundary of a phase diagram for a pure substance?
