Question

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

Answer 1

temperature and mechanism

Step-by-step explanation:

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

`k=Ae^{(-E_(a) )/(RT) }`

where k=equilibrium constant

A=pre-exponential factor

`E_(a)`=Activation energy

T=temperature

R=Universal gas constant

It is clear that k depends only on temperature and activation energy.

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