In the reaction A ----> B + C deltaH is negatvie,what effect would increasing the temperature will have on equilibrium ?

Home >> Practice Problems

When the delta H is negative it means that this reaction is a exothermic reaction , so heat is going to be a product , so the reaction is :

A ----> B + C + heat

Temperature is a measure of Heat increasing the T means increasing the Heat and as in this reaction heat is a product  increasing the temperature according the Le chatelier's principle, we would expect the system to shift to the left .


this is a exothermic reaction , in this case increasing the temperature will shift the equilibrium to the left and more reactant will form.
