What effect would a catalyst have on the reaction A2 plus 2B ---- 2AB?
A catalyst would increase the rate of the reaction by providing an alternative pathway with lower activation energy. This would allow the reaction to occur more quickly without being consumed in the process. The equilibrium concentrations of the reactants and products would remain the same.
What is the opposite reaction of a Catalyst?
The opposite of a catalyst is an inhibitor, something that suppresses or slows a reaction.
Which would increases the reaction rate?
Temperature
Would a catalyst cause an endothermic reaction to become exothermic?
No, a catalyst does not change the overall energy of a reaction. It only lowers the activation energy required for the reaction to occur. Therefore, a catalyst cannot change an endothermic reaction into an exothermic one.
What does a catalyst do to the rate of a chemical reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction without changing the substance. It does this by reducing the minimal reaction energy. A catalyst is not used up in a reaction therefore they last indefinitely.

What substance increases the rate of a reaction but is not itself changed by the reaction?
It's called a catalyst. A catalyst is present during a chemical reaction but does not participate as a reactant or product. A catalyst lowers the reaction's activation energy, making the reaction easier to happen. In the equation for a chemical reaction, the catalyst's formula appears in small notation above the "yield" arrow (format won't let me show you an example.) An example of a catalyst is potassium iodide (KI) speeding up the decomposition of hydrogen peroxide (H2O2).
Does a catalyst make a reaction exothermic?
I honestly think it would because a catalyst lowers the activation energy, the amount of energy needed to complete the reaction. Since the activation energy is lower, it is absorbing less energy. I guess if its becoming less endothermic, its becoming more exothermic. Hope this helped!
What do you think the diagram would look like if a catalyst were added?
If a catalyst were added to a reaction diagram, it would typically be shown as a separate step or pathway with lower activation energy compared to the uncatalyzed reaction. The overall energy profile of the reaction would be shifted downward, indicating that the catalyst lowers the activation energy required for the reaction to proceed, leading to an increased reaction rate.
What is the effect of the addition of a catalyst on the rate of a chemical reaction?
A catalyst increases the rate of a chemical reaction by providing an alternative pathway with lower activation energy. This allows for more reactant molecules to overcome the energy barrier and form products more quickly, without being consumed in the process.
How would you speed up a reaction without a catalyst?
heat the vessel the reaction is taking place!
How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
Adding a catalyst to the mixture would not affect the equilibrium concentration of H2O. A catalyst speeds up the rate of the forward and reverse reactions equally, without changing the position of the equilibrium. This means that the equilibrium concentration of H2O would not be affected by the presence of a catalyst.
What effect does a promoter catalyst have on the position of the equilibrium?
By definition a catalyst cannot affect equilibrium because although a catalyst can speed up a chemical reaction, it cannot change the thermodynamics of it, and equilibrium is determined solely by thermodynamics. A catalyst may help a system reach equilibrium more quickly, but it will not change it. One possible way a catalyst could affect equilibrium is by introducing a catalyst that affects a different reaction involving the substrate or products of the original reaction, but this would be cheating since the system would no longer be closed.
