Question

Equilibrium constant for the reaction of iodine with propane according to the following was determined. Some results obtained at 545 K were as given ahead:

Initial Pressure (mm Hg)		Equilibrium Pressure (mm)
I2	C3H6	HI	HI	C3H5I
23.9	505.8	0	1.80	1.80
16.1	355.3	1.62	2.27	0.645

Calculate equilibrium constant according to the following equation,

I₂(g) + C₃H₆(g) ⇋ C₃H₅I(g) + HI(g)

Answer 1
