Exothermic reactions release heat, raising temperature; endothermic absorb heat, lowering temperature.
Energy is needed to break bonds and released when new bonds form.
Products lower in energy than reactants indicate an exothermic reaction.
The minimum energy required for a reaction to occur.
A catalyst lowers the activation energy peak without changing reactant or product energy.
Bond breaking requires energy; bond making releases energy.
Exothermic reactions release more energy forming bonds than is absorbed breaking them.
It is endothermic, absorbing heat from the surroundings.
More particles have sufficient energy for successful collisions.
Initial energy is needed to break bonds before more energy is released.
The activation energy peak is lower, but start and end energy levels remain unchanged.
Energy is needed to overcome the forces holding atoms in a bond.
The overall energy change is +150 kJ/mol, indicating an exothermic reaction.
They lower activation energy, speeding up reactions and reducing costs.
