Write the equilibrium‑constant expression for the reaction a ( s ) + 3 b ( l ) − ⇀ ↽ − 2 c ( aq ) + d ( aq ) in terms of [ a ] , [ b ] , [ c ] , and [ d ] , as needed. note that k c , which is sometimes symbolized as k eq , denotes that the equilibrium constant is expressed using molar concentrations. for this question, k c means the same thing as k eq .

The expression of equilibrium constant is

Explanation:

Equilibrium constant in terms of concentration 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

For a general chemical reaction:

The expression for is written as:

Concentration of pure solids and pure liquids are taken as 1 in the expression.

For the given chemical reaction:

The expression of for above equation follows:

Hence, the expression of equilibrium constant is

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
