Chapter 12, Problem 107CP

A mixture of N₂, H₂, and NH₃ is at equilibrium [according to the equation ${\mathrm{N}}_2\left(g\right)+3{\text{H}}_2\left(g\right)\rightleftharpoons 2{\text{NH}}_3\left(g\right)$] as depicted below:

The volume is suddenly decreased (by increasing the external pressure) and a new equilibrium is established as depicted below:

a. If the volume of the final equilibrium mixture is 1.00 L, determine the value of the equilibrium constant, K. for the reaction. Assume temperature is constant.

b. Determine the volume of the initial equilibrium mixture assuming a final equilibrium volume of 1.00 L and assuming a constant temperature.
