consider the general reversible reaction.\naa + bb⇌cc + dd\nwhat is the equilibrium constant expression for the given system?\n○ keq = \\frac{ccdd}{aabb}\n○ keq = \\frac{cd}{ab}\n○ keq = \\frac{a^ab^b}{c^cd^d}\n○ keq = \\frac{c^cd^d}{a^ab^b}
Answer
Explanation:
Step1: Recall equilibrium - constant formula
For a general reversible reaction (aA + bB\rightleftharpoons cC + dD), the equilibrium - constant expression (K_{eq}) is the ratio of the product of the concentrations of the products raised to their stoichiometric coefficients to the product of the concentrations of the reactants raised to their stoichiometric coefficients.
Step2: Write the correct expression
The equilibrium - constant expression (K_{eq}=\frac{[C]^c[D]^d}{[A]^a[B]^b}), where ([A]), ([B]), ([C]), and ([D]) are the molar concentrations of (A), (B), (C), and (D) respectively, and (a), (b), (c), and (d) are their stoichiometric coefficients in the balanced chemical equation.
Answer:
(K_{eq}=\frac{[C]^c[D]^d}{[A]^a[B]^b}) (the fourth option)
