If the temperature of a reaction increases what happens to the value of the equilibruim constant
🔄 Click to see definition
Definition1/8
Equilibrium constant changes when temperature changes. For an
endothermic reaction, the equilibrium constant increases with
temperature while for an exothermic reaction equilibrium constant
decreases with increase in temperature. Equilibrium constants are
only affected by change in temperature.
