- 12. Explain the color change that occurred the diluted solution was heated. (How would the reaction shift if Kc went up? How did increasing the temperature affect the value of Kc? What is the sign of ΔH in the reaction?) HINT : Endothermic reactions have a positive ΔH. Exothermic reactions have a negative ΔH.
