The decomposition of HI(g) is represented by the equation2HI(g)H2(g)+I2(g) The following experiment was devised todetermine the equilibrium constant of the reaction. HI(g) isintroduced into five identical 400-cm3 glass bulbs and the fivebulbs are maintained at 623 K.The amount of I2 produced over timeis measured by opening each bulb and titrating the contents with0.0150 M Na2S2O3(aq). The reaction of I2 with the titrant isI2+2Na2S2O3Na2S4O6+2NaI
