1.In a closed vessel,4 moles of hydrogen & 3 moles of iodine were heated at 450K . At equilibrium, 5 moles of HI were formed.Calculate, the value of Kc. 2.Calculate the equilibrium constant , for the reaction, if one mole of phosphorous pentachloride is heated in a closed vessel of volume 10metercube. At the equilibrium , 0.40 mole of phosphorous trichloride , was found to be present.
