Gaseous hydrogen and gaseous iodine react together to form hydrogen iodide. H 2 + I 2

Question:

Gaseous hydrogen and gaseous iodine react together to form hydrogen iodide.

H₂ + I₂ ⇋ 2HI

a. The graph shows how the amount of hydrogen iodide varies with time in a 1.00 dm³ container. The initial amounts of hydrogen and iodine were 1.00mol H₂ and 1.00mol I₂.

Draw a similar graph to show how the number of moles of hydrogen varies with time.

b. Calculate the number of moles of iodine present at equilibrium.

c. i. Write the equilibrium expression for K_c for the reaction between gaseous hydrogen and iodine.

ii. Calculate the value of K_c and give the units.
