Equilibrium Concentration Calculation in Chemical Reactions
What is equilibrium concentration?
Equilibrium concentration is defined as a situation where the rate of forward and reverse reactions in a chemical process are equal. The equilibrium will adjust to minimize the impact of a change in a substance's concentration. If a reactant's concentration rises, the equilibrium will change in favor of the reaction that utilises it, causing the reactant concentration to fall.
Calculate the equilibrium concentrations of each gas at 430 ∘C.
Kc = [ Product ]² / [ Reactant ]
Kc = [ 0.905 ]² / [ 0.463 ] [ 0.309 ]
Kc = [ 0.8190 ] / [ 0.14306 ]
Kc = 5.72 M
Equilibrium concentration in a chemical reaction is a crucial concept that helps in understanding the dynamics of the reaction. In the given scenario where a mixture of 0.463 M H2, 0.309 M I2, and 0.905 M HI is heated to 430 °C, the equilibrium concentrations of each gas at 430 °C have been calculated to be 5.72 M.
This calculation is based on the equilibrium constant expression, Kc, which is defined as the ratio of the concentrations of the products to the concentrations of the reactants, each raised to the power of their stoichiometric coefficients in the balanced chemical equation. By substituting the given concentrations into the equation and calculating Kc, we are able to determine the equilibrium concentrations of the gases at the specified temperature.
Understanding equilibrium concentration is essential in predicting and controlling chemical reactions in various processes, including industrial applications and environmental studies. By manipulating the conditions that affect equilibrium, such as temperature, pressure, and concentration, scientists and engineers can optimize reactions for desired outcomes.
