Are gases included in equilibrium expression?
The answer is that those substances that are in aqueous solution would continue to be included in the equilibrium constant expression as molar concentrations, with only the gases being entered as pressures in atmospheres.
What is the general equilibrium expression?
Since kf and kr are constants, the ratio of kf divided by kr must also be a constant. This ratio is the equilibrium constant for the reaction, Kc. The ratio of the concentrations of the reactants and products is known as the equilibrium constant expression.
How is equilibrium constant expression written?
Which is the correct equilibrium expression for the reaction?
Correct answer: The equilibrium expression is defined as the ratio of the concentration of products divided by the concentration of the reactants. Each reactant or product is raised to the power corresponding to its coefficient in the balanced chemical equation.
What is the equilibrium constant expression of aA bB ⇌ cC dD?
Equilibrium Constant For the general reaction aA + bB –> cC + dD Kc is the ratio of the product concentrations divided by the reactant concentrations, with each concentration raised to the power of its coefficient in the balanced chemical reaction.
How is concentration of gas expressed?
By inverting the ideal gas law equation and solving for the concentration, n/V, or moles per liter, the concentrations of the gases are expressed by their partial pressures divided by RT. 4) Now, since we have solved for the concentrations of each gas component, we write them in terms of concentration activities.
