2. Consider a cup of black tea. Well, more specifically, the tea in the cup. Chemical analysis was performed on the black tea (published in: Food & Function, 2013, 4, 10; DOI: 10.1039/c2f030093a), and the following chemical specifies were detected: 4 different molecules belonging to the catechin class, and 4 different molecules belonging to the theaflavin class. Basic frameworks associated with these molecule classes are provided below for reference: OH OR OH OH ОН HO O ОН HO но. R "OH OR OR OH OH Catechin, general framework Theaflavin, general framework Assuming that black tea is composed of these 4 catechins, 4 theaflavins, water, and caffeine, please determine: (a) the phase rule equation that should govern this black tea sample. [1 mark] (b) if P = 10, how many degrees of freedom would be present? Would this be represented on the phase diagram as an area, line, point, or something else? [2 marks] (c) How many phases could be simultaneously in equilibrium with one another for this system? (1 mark]
