How does a catalyst reduce activation energy

Web• Catalyst provides an alternate pathway or reaction mechanism by reducing the activation energy and hence lowering the potential energy barrier. Lower the value of activation energy faster will be the rate of a reaction. • A catalyst does not alter Gibbs energy, ΔG of a reaction. • A catalyst does not change the equilibrium constant of ... WebCatalyst lower activation energy is: By altering the reaction's transition state, a catalyst lowers the activation energy. After that, the reaction follows a different mechanism than …
