what is hypothetical equilibrium?
Answers
Answer:
Consider the hypothetical reversible reaction in which reactants A and B react to form products C and D. This is because equilibrium is defined as a condition resulting from the rates of forward and reverse reactions being equal. ...

Explanation:
Consider the hypothetical reversible reaction in which reactants A and B react to form products C and D. This equilibrium can be shown below, where the lower case letters represent the coefficients of each substance.
aA + bB rightleftarrows cC+dD
As we have established, the rates of the forward and reverse reactions are the same at equilibrium, and so the concentrations of all of the substances are constant. Since that is the case, it stands to reason that a ratio of the concentrations for any given reaction at equilibrium maintains a constant value. The equilibrium constant (Keq) is the ratio of the mathematical product of the concentrations of the products of a reaction to the mathematical product of the concentrations of the reactants of the reaction. Each concentration is raised to the power of its coefficient in the balanced chemical equation. For the general reaction above, the equilibrium constant expression is written as follows:
K_{eq}=frac{left [ Cright ]^c left [ Dright ]^d}{left [ Aright ]^a left [B right ]^b}
