Chlorine gas reacts with fluorine gas to form chlorine trifluoride. Cl2( g) + 3 F2( g)¡2 ClF3( g) A 2.00-L reaction vessel, initially at 298 K, contains chlorine gas at a partial pressure of 337 mmHg and fluorine gas at a partial pressure of 729 mmHg. Identify the limiting reactant. Determine the theoretical yield of ClF3 in grams.
