Consider the following reaction at 425 °C:
H2 (g) + I2 (g) = 2HI(g)
An equilibrium mixture contains 1.22 x 10-2 mol H2, 1.22 x 10-2 mol I2 and 9.00 x 10-2
mol HI in a 5.00 L reactor. At a certain instant, a valve is opened, and 1.40 × 10-2 mol of I2
is added to the reactor.
1.1 Determine the value of Ke at 425 °c
1.2 Once equilibrium has been re-established, the concentration of hydrogen iodide gas in the
reactor was measured to be 2.03 x 10-2 M. Determine the concentration of the other
species present in the system for this set of conditions.
