Temperature change

[Gerald Bernal1I]

Why does temperature change the K value, does it have to do with changing reaction rate?

[nicolely2F]

Increasing the temperature makes the reaction environment more energetic, and this extra energy is used in breaking chemical bonds, which speeds up reaction. It affects K because the formation of product may require heat (endothermic), so if the temperature raises then the forward reaction will be favored and the concentrations at equilibrium will change.

Why do changes in concentration, pressure, and volume have no effect on the K value?

[Phuong Tran 1G]

If the temperature increases, would the value of K increase too?

[Marni Kahn 1A]

Why do changes in concentration, pressure, and volume have no effect on the K value?

The constant K is temperature-dependent, meaning that only changes in temperature will affect the value of K.

[Katie Kyan 2K]

If the temperature increases, would the value of K increase too?

When changing temperature the value of K will increase or decrease depending on whether the reaction is endothermic or exothermic. If the forward reaction is exothermic, increasing the temperature shifts the reaction to the left which means the value of K will decrease. Conversely, if the forward reaction is endothermic, increasing temperature will shift the reaction to the right meaning that K will increase.
