The equilibrium-constant expression depends on the of the reaction. group of answer choices temperature stoichiometry mechanism the quantities of reactants and products initially present stoichiometry and mechanism

temperature and mechanism

Explanation:

Arrhenius equation gives us the idea about the factors affecting equilibrium constant.It is given as:

where k=equilibrium constant

          A=pre-exponential factor

          =Activation energy

          T=temperature

          R=Universal gas constant

Activation energy of a reaction is different for different mechanisms or pathways.Hence k depends on both temperature and mechanism.

i think   the answer is c hope i'm right

it's c (engineer's do their work with mechanical stuff not on any living being)
