What must happen for reactants to change into a product?
For reactants to change into a product, they must undergo a chemical reaction, which involves breaking and forming chemical bonds. This process typically requires an input of energy to overcome the activation energy barrier, allowing the reactants to collide with sufficient energy and proper orientation. Additionally, the presence of catalysts can facilitate the reaction by lowering the activation energy required. Once the reactants interact appropriately, they rearrange to form the resulting products.
Whats the difference between activation energy and the change of energy in a PE diagram?
Activation energy is the minimum energy required for a reaction to occur, while the change in energy in a potential energy diagram represents the difference in energy between the reactants and the products of a reaction. Activation energy is specific to the transition state of a reaction, whereas the change in energy is a measure of the overall energy difference between reactants and products.
What is a change which means the products can't be returned back to the reactants?
A change that makes it difficult or impossible for products to revert back to reactants is increasing the temperature to exceed the activation energy barrier for the reverse reaction, altering the pH to a level that favors product stability, or physically removing the product from the reaction environment.
Is it true that another way to control the rate of a reaction is to change the activation energy needed?
Yes, altering the activation energy required for a reaction can impact the reaction rate. Lowering the activation energy makes it easier for the reaction to occur, speeding up the rate, while increasing the activation energy slows down the rate. This is often achieved by using catalysts to provide an alternative reaction pathway with lower activation energy.
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
When is activation energy the same for forward and reverse reactions?
Activation energy is the same for the forward and reverse reactions at equilibrium, where the rates of the forward and reverse reactions are equal. At this point, the activation energy represents the energy barrier that must be overcome in either direction to proceed with the reaction.
Why is the activation energy of an endothermic reaction is at least as large as its enthalpy?
The activation energy of an endothermic reaction is at least as large as its enthalpy change because the reactants require a minimum amount of energy to reach the transition state where bond-breaking and bond-forming occur. The enthalpy change represents the overall energy difference between reactants and products but does not account for the energy needed to overcome the energy barrier (activation energy) for the reaction to proceed.

The amount of energy which a system has to have in order for a chemical change to take place?
The activation energy.
What would happen if there wasn't enough activation energy in a chemical change?
If the activation energy for a particular chemical reaction was not available the reaction cannot proceed. The chemical reaction cannot proceed without activation energy and cannot form products.
How would a catalyst change the reaction energy diagram?
The overall enthalpy change in a common reaction would not change. Only the path to get there would change. A catalyst basically lessens the activation energy required to get the reaction to take place.
