The minimum energy needed for a reaction to proceed, known as the activation energy, stays the same with increasing temperature.
What factors affect the activation energy?
activation energy: The minimum amount of energy that molecules must have in order for a reaction to occur upon collision.
- Reactant Concentrations. Raising the concentrations of reactants makes the reaction happen at a faster rate. ...
- Surface Area. ...
- Pressure. ...
- Temperature. ...
- Presence or Absence of a Catalyst. ...
- Nature of the Reactants.
How does temperature affect activation energy Arrhenius equation?
Although a higher temp increases the rate of the reaction by increasing kinetic energy, it does not directly affect the energy needed for the reaction to proceed. The higher temp will increase the rate at which it reaches the activation energy but it doesn't directly change it.
