Answer :
Answer:
(A) stoichiometry
Explanation:
For example, Consider the reaction of the type ,
aA + bB-----> cC +dD
where b, a, d, and c are the stoichiometric coefficients for the balanced equation .
The equilibrium constant expression is denoted by K ,
equilibrium constant is the product's concentration each raised to the power of its corresponding stoichiometries , divided by reactant's concentration each raised to the power of its corresponding stoichiometries .
