Answer:
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
     [tex]E_{a}[/tex]=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.
