4.23 predict the effects of changing the pressure and temperature on the equilibrium positions in reversible reactions

4.23 •exothermic releases energy (heat), endothermic needs it

        •raise temperature = endothermic reaction will increase in order to use the energy

        •reduce temperature = exothermic reaction will increase giving energy out 

        •raise pressure = increase the reaction of producing fewer molecules

        •reduce pressure = increase the reaction of producing more molecules
