powerpoint presentation * methods of catalyst regeneration a y c a t l s i s * what is a catalyst ? catalyst is a substance that increases the rate of the reaction at which a chemical system approaches equilibrium , without being substantially consumed in the process. catalyst affects only the rate of the reaction,i.e.kinetics. it changes neither the thermodynamics of the reaction nor the equilibrium composition. * activation energy activation energy : the energy required to overcome the reaction barrier. usually given a symbol ea or ∆g≠ the activation energy (ea) determines how fast a reaction occurs, the higher activation barrier, the slower the reaction rate. the lower the activation barrier, the faster the reaction * catalyst lowers the activation energy for both forward and reverse reactions. activation energy * activation energy this means , the catalyst changes the reaction path by lowering its activation energy and consequently …
