Question

Consider the general reversible reaction.

Answer 1

Answer: $K=\frac{[D]^d[C]^c}{[B]^b[A]^a}$

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as $K_{eq}$

$aA+bB\rightleftharpoons cC+dD$

The expression for $K_{eq}$ for the given reaction is written as:

$K=\frac{[D]^d[C]^c}{[B]^b[A]^a}$

where a, b , c and d are respective stoichiometric coefficients for A, B, C and D.
