Chemical Equilibrium

Q. Consider the following dimerization reaction of substance B B2(g) 2B(g) H°dimer A substance B was vaporized in vessel of volume 42.9 cm3 at 874 K, the vessel was wrapped and external pressure was 203.8 kPa, the mass of present in the wrapped container was 0.1038 g. A second trial with the same vessel at 942 K, the mass of substance found 0.076 g.
