1 Answer the following questions: a. For a pure component, on the vapor pressure curve, vapor and liquid phases coexist in equilibrium. True or False b. If a component is at a critical temperature, then its vapor pressure is equal to its critical pressure. True or False c. T. and P, of methane is -116°F and 661 psia. If a PVT cell contains pure methane at 32°F and 1000 psia, then the state of methane is fully super- critical. True or False d. Every pure-component system is invariant at triple point. True or False e. A PVT cell contains n-butane at 100.0°F and 1000 psia. The state of n-butane in the cell is partially supercritical liquid-like. True or False f. Four degrees of freedom are required for a three-component system to exist in single phase. True or False g. Cricondenbar and critical pressure of a certain hydrocarbon mixture were found to be same. Is this possible. Yes or No? h. A hydrocarbon mixture can exist in two phases even above its critical pres- sure and critical temperature. True or False i. The intensive properties of the vapor and liquid phase at critical point are substantially different from each other. True or False
