Suppose H2(g) and I(g) are sealed in a flask at T = 400 K with partial pressures PH, = 1.320 atm and R, = 1.140 atm. At this temperature H, and I, do not react rap- idly to form HI(g), although after a long enough time they would produce HI(g) at its equilibrium partial pressure. Suppose, instead, that the gases are heated in the sealed flask to 600 K, a temperature at which they quickly reach equilibrium: H2 (g) + I2(g)=2 HI(g) The equilibrium constant for the reaction is 92.6 at 600 K: P PH, P, = 92.6 (a) What are the equilibrium values of R1,, P., and PHI at 600 K? (b) What percentage of the I, originally present has reacted when equilibrium is reached?
