When a 0.218 mol sample of hydrogen iodide was heated in a flask of volume Vdm3 the following equilibrium was established at 700k 2Hl(g) > H2(g) + l2(g) The equilibrium mixture was found to contain 0.023 mol of hydrogen A) calculate the number of moles of iodine and the number of moles of hydrogen iodide in the equilibrium mixture B) write an expression for Kc for the equilibrium C) state why the volume of the flask need not be known when calculating a value for Kc D) calculate the value of Kc at 700k E) calculate the value of the Kc at 700K for the following equilibrium H2(g)+ l2(g) > 2Hl(g)
