. Consider the following 3 systems: a. A binary mixture with vapor-liquid equilibrium, both components are generally present in
both phases. b. The reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. c. The reaction between steam and methane to form hydrogen gas occurs in the gas phase. Carbon monoxide and carbon dioxide are also produced. d. How many degrees of freedom (ℱ) are there for each system? If ℱ > 0 then which intensive variables would you fix? What would you conclude if ℱ = 0 or ℱ < 0 ?
