The presence of a catalyst will lower a reaction's activation energy.
Activation energy graphs show the energy changes that occur during a chemical reaction. They typically have a peak representing the activation energy required for the reaction to occur. By analyzing these graphs, scientists can determine the rate of the reaction and predict how likely it is to happen. This helps in understanding the mechanisms and kinetics of chemical reactions, as well as in designing and optimizing reaction conditions for desired outcomes.

Thermodynamics
The Gibbs free energy diagram helps determine if a chemical reaction is likely to occur by showing the energy changes involved. If the overall change in Gibbs free energy is negative, the reaction is thermodynamically feasible and likely to happen.
The reaction described by curve B is occurring with a catalyst.
The difference between curve A and curve B on an energy diagram is most likely due to the activation energy required for the reaction. Curve A likely represents a reaction with a higher activation energy, resulting in a slower reaction rate compared to curve B, which represents a reaction with a lower activation energy and a faster reaction rate.
It indicates how likely a reaction might be, but there are no hard rules. Low activation energy indicates that the reaction is likely to take place spontaneously. In most cases, the reaction must be exothermic as well. There are lots of exceptions to these simple rules. For any reaction to occur, the reactants must gain at least the activation energy.
The Arrhenius equation is: Ea = -RT ln(k/A) where Ea - activation energy R - universal gas constant ln - logarithm k - speed constant T - temperature in kelvins
In Experiment 24, you are likely investigating the relationship between the rate of a chemical reaction and the concentration of reactants (rate law). Activation energy refers to the minimum energy required for a reaction to occur. By studying the rate law and activation energy, you can gain insight into the factors influencing the speed of a chemical reaction.

Enzymes lower the activation energy required for a chemical reaction to occur, allowing reactions to happen more efficiently at lower temperatures in biological systems. This reduction in activation energy enables faster reaction rates and promotes metabolic processes in living organisms.
The enzyme will act as a catalyst, a compound that lowers that activation energy of the reaction, and therefore, increase the rate of the reaction.
A catalyst, like enzymes.A catalyst is a substance that lowers the activation energy for a reaction and allows the process to speed up. The catalyst does not react with the substance so that it is 'used up'; in other words, it's reusable and comes out of the reaction unchanged.

If a reaction takes billions of years to complete, it likely has a very high activation energy barrier. This indicates that only a very small fraction of reactant molecules possess the required energy to overcome the barrier and proceed to product formation over such a prolonged timescale.
