**Writing Equilibrium Expressions**

In order to write the equilibrium expression for a system in a state of equilibrium you need to know:

the balanced equation for the reaction

the phases (solid, liquid, gas, or dissolved) of each species involved in the reaction.

Writing expressions for Kc

Writing expressions for Kp

**What concentration of S2 can be expected when 0.200 mole of H2S comes to equilibrium at 1100 K in an otherwise empty 1.00-L vessel?**

We write the equation and place quantities at the initial condition and at various stages below the formula. We assume *x* mol of S2 is formed, and this leads to the formation of 2*x* moles of H2. Since -2*x* moles of H2S is required, the equilibrium concentration of H2S is 0.200 - 2*x*. Thus, we have

The Graphical Approach

By now, we are familiar with graphs of supply curves and demand curves. To find market equilibrium, we combine the two curves onto one graph. The point of intersection of supply and demand marks the point of equilibrium. Unless interfered with, the market will settle at this price and quantity. Why is this? At this point of intersection, buyers and sellers agree on both price and quantity. For instance, in the graph below, we see that at the equilibrium price p*, buyers want to buy exactly the same amount that sellers want to sell.

**5-2 Equations of Equilibrium**

Using a small element of material, D *x D y D z*, from a linear elastic body as shown in the figure, we can write the equations of equilibrium for the stress components acting on the faces of the element. Since the stresses change as one moves from point to point within the body, a variation in each stress term is considered using a first order Taylor series expansion. (For simplicity only the *x* normal and *xy* shear stresses are shown.)

Reactions involving more than one phase are said to be heterogeneous. Some examples:

Bear in mind that terms related to condensed phases (solids and liquids) do not appear in equilibrium expressions.

Vapor pressures of solid hydrates

A particularly interesting type of heterogeneous reaction is one in which a solid is in equilibrium with a gas. The sublimation of ice illustrated in the above table is a very common example. The equilibrium constant for this process is simply the partial pressure of water vapor in equilibrium with the solidâ€” the vapor pressure of the ice.
