Write the expression for the equilibrium constant for the following reactions ? 2SO2(g) + O2(g) -------> 2SO3(g)
What is equilibrium constant?
What is equilibrium constant?
For a chemical equilibrium, the equilibrium constant is defined as the ratio between the product of the equilibrium concentrations of the products and the product of the equilibrium concentrations of the reactants, all raised to the power of their respective stoichiometric coefficients.
For a general form equilibrium reaction
Here
Now take a look at the equilibrium given to you
More specifically, the equilibrium constant will be
This time, you have one product and two reactants, so the equilibrium constant will take the form

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- For the reaction, #K_c = 0.513# at 500 K. #N_2O_4(g) rightleftharpoons 2NO_2(g)#. If a reaction vessel initially contains an #N_2O_4# concentration of 0.0500 M at 500 K, what are the equilibrium concentrations of #N_2O_4# and #NO_2# at 500 K?
- A saturated solution of #PbBr_2# is prepared by dissolving the solid salt in water. The concentration of #Pb_2^+# in solution is found to be 0.0115 M. What is the Ksp for #PbBr_2#?
