If the reaction requires heat (endothermic reaction) to form more products, then the reaction will shift to the right favoring more product formation. If the reaction gives off heat (exothermic reaction) while forming product, then the reaction will shift to the left favoring reactant formation. I hope this helps! shwe san eain
