Question
A mixture of hydrogen and iodine in the mole ration 1.5:1 is maintained at 450oC. After the attainment of equilibrium H2(g)+I2(g)⇌2HI(g), it is found on analysis that the mole ratio of I2 to HI is 1:18. Calculate the equilibrium constant and the number of moles of each species present under equilibrium, if initially, 127grams of iodine were taken.
