Exothermic temp change
WebWhereas, if you increase concentration, pressure/volume will change the direction of the rxn but not the Keq value. Using the Keq=product/reactant. If you increase temp for endothermic rxn (forward direction), the Keq will increase because product is favoured. If you increase temp for exothermic rxn (forward direction), the Keq will decrease ... WebThe overall change in energy in a reaction is the difference between the energy of the reactants and products. Exothermic reactions The diagram shows a reaction profile for an exothermic reaction.
