Aug 14, 2020 · Calculate the final concentrations of all species present. Check your answers by substituting these values into the equilibrium constant expression to obtain \(K\). Solution
- The reaction between gaseous sulfur dioxide and oxygen is a key step in the industrial synthesis of sulfuric acid: \( 2SO_{2}\left ( g \right ) + O_{2}\left ( g \right ) \rightleftharpoons 2SO_{3}\left ( g \right ) \)
- A 1.00 mol sample of NOCl was placed in a 2.00 L reactor and heated to 227°C until the system reached equilibrium. The contents of the reactor were then analyzed and found to contain 0.056 mol of Cl2.
- The water–gas shift reaction is important in several chemical processes, such as the production of H2 for fuel cells. This reaction can be written as follows
- In the water–gas shift reaction shown in Example 10, a sample containing 0.632 M CO2 and 0.570 M H2 is allowed to equilibrate at 700 K. At this temperature, K = 0.106.
If a mixture of gases that initially contains 0.0150 M H 2 and 0.0150 M CO 2 is allowed to equilibrate at 700 K, what are the final concentrations of all substances present? Solution. The initial concentrations of the reactants are [H 2] i = [CO 2] i = 0.0150 M.
What is the concentration of each species in the flask when equilibrium has been established? The equation for the reaction is as follows: H 2 (g) + Br 2 (g) 2 HBr (g) K c = 64 @ 700 K. Write the equilibrium expression for the reaction. Since K c is used in this problem, check to see if the given quantities are in moles per liter (molarity).
Chemical equilibrium: The condition in a reaction when the concentrations of reactants and products cease to change. At this point opposing reactions are occurring at equal rates. Previous examples of equilibrium: . vapor pressure above a liquid is in equilibrium with the liquid.

Constant concentrations. At equilibrium, the concentrations of the substances participating in the equilibrium are constant. Although individual reactant molecules may be reacting to form product molecules and individual product molecules may be reacting to re-form the reactants, the concentrations of the reactants and the products remain constant.
