Figure 1 Enzymes lower the activation energy of the reaction but do not change the free energy of the reaction Here the solid line in the graph shows the energy required for reactants to turn into products without a catalyst The dotted line shows the energy required using a catalyst What is activation energy It is the nrg necessary to get the reaction to go forward even if it is an exergonic reaction What is activation energy or blue line coincides with the point where the bonds in the reactants of the reaction are weakest It is also called a transition state
Jul 18 2014 nbsp 0183 32 The difference in the activation energy of substrate and product is indicated on the graph If P is at a lower level than S then the reaction is an exothermic reaction The difference in average energy content of S from that of its transition state is called activation energy The activation energy is the energy difference between reactant and transition state The activation energy of a reaction is usually denoted by Ea and given in units of kilojoules per mole kJ mol or Kilocalories per moles Kcal mol and is defined as

In chemistry activation energy is the minimum amount of energy required for a chemical reaction The activation energy can be thought of as the magnitude of a potential barrier that the reacting molecules need to overcome to initiate a reaction and convert into products A catalyst is a substance that increases the rate of a chemical reaction by reducing the amount of energy needed to start that reaction This is called lowering the activation energy
Feb 26 2022 nbsp 0183 32 The free energy graph can be used to determine whether the reaction will be spontaneous or not by evaluating the G G can be found by subtracting the free energy of the reactants from the free energy of the products Enzymes catalyze chemical reactions IB Topic 2 5 We know that they have an active site where the substrate binds and that when a substrate collides with an active site then a reaction occurs The reason that enzymes speed up these reactions
