WebpKa value is the negative base -10 logarithm of the acid dissociation constant (Ka) of a solution. pKa = -log [Ka] How does pKa change with temperature? An endothermic reaction required heat during the reaction. Increase the dissociation constant (Ka) with an increase in temperature. Higher the value of Ka lowers the value of pKa. Web1.
