Heating HI(g) at 425 degree C causes some of this compound to decompose, forming H2(g) and I2(g). Eventually, the amounts of the three species do not change further; the system has reached equilibrium. (at this point, approximately 22% of the HI has decomposed.) Describe what is happening in this system at the molecular level.
