Temperature and the equilibrium constant

Postby Artin Allahverdian 2H » Mon Jan 14, 2019 8:26 pm

Why does a change in temperature result in a change in the equilibrium constant for a reaction? Is temperature the only thing that can alter the equilibrium constant or are there other variables that can affect it as well?

I believe temperature is the only factor that can change the K-value.

A change in temperature will cause an endothermic reaction to shift to the right. It will then reach a new equilibrium at this new temperature, in which products are higher in concentration than before and reactants are smaller in concentration. At this new equilibrium, the k-value will be much higher.

As mentioned before, temperature is the only parameter that affects the equilibrium constant; this occurs as a result of how temperature actually affects the internal energy of the system, shifting the potential and kinetic energies of involved reactants and products.
