Consider the following reaction: pcl5(g)⇌pcl3(g)+cl2(g) you may want to reference (pages 380 - 392) sections 10.3 to 10.5 while completing this problem. part a select the equilibrium-constant expression for the reaction.

The equilibrium constant expression for the reaction is written below

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:

For the given chemical reaction:

The expression of equilibrium constant for the reaction is:

Hence, the equilibrium constant expression for the reaction is written above.

i would say b

explanation:

but i think i would need more information than that
