Predicting the Direction of Approach to Equilibrium
At 448 °C. the equilibrium constant Kc for the reaction
is 50.5. Predict in which direction the reaction proceeds to reach equilibrium if we start with 2.0 x 10-2 mol of HI, 1.0 x 10-2 mol of H2. and 3.0 x 10-2 mol of I2 in a 2.00-L container.
Which of the following statements accurately describes what would happen to the direction of the reaction described in the sample exercise above, if the size of the container were different from 2.00 L?
(a) The reaction would proceed in the opposite direction (from right to left) if the container volume were reduced sufficiently., (b) The reaction would proceed in the opposite direction if the container volume were expanded sufficiently., (c) The direction of this reaction does not depend on the volume of the container.
