A vessel with a volume V = 0.5 l contains m = 1 g of vaporous iodine (J2). At a temperature of T=1000°C, the pressure in the vessel turned out to be equal to P=700 mmHg. Art. Find the degree of dissociation of iodine molecules J2 into iodine atoms J under these conditions. Molecular weight of iodine J2 M = 254. Note. The degree of dissociation is the ratio of the number of dissociated molecules to the total number of molecules before dissociation.
