Equilibrium constant and K

The addition of heat in a reaction changes the value of K, so is this a permanent effect due to chemical bonds forming/breaking? Or will K revert to its original value once heat is removed? Thanks!

I believe K will revert to its normal value once the original amount of heat is restored.

There is a direct relationship between temperature and the value of K. When the temperature increases, the value of K increase. And when the temperature decreases, the value of K decreases.

So if the heat is removed, then the value of K will revert to its original value.
