What does a catalyst not do?
Catalysts do not change the postition of the reaction's equilibrium. Adding a catalyst will increase the rate of reaction, but it will do this by providing another pathway for the reaction to occur acros, meaning a lower activation enthalpy is needed. :)
Does a catalyst affect enthalpy of a reaction?
What effect does a catalyst have on the mechanism of a reaction? It usually binds to the reactant(s) and orients the reactants optimally to speed up the reaction. Remeber the lock and key model for enzymes? Or even how Heterogeneous catalysis work by holding onto the reactant to orient it correctly. Stop googling and start thinking.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
How does the catalyst affect the Keq value of a reacti on?
A catalyst does not affect the value of the equilibrium constant (Keq) of a reaction. The presence of a catalyst increases the rate of both the forward and reverse reactions equally, allowing the system to reach equilibrium more quickly but does not change the final equilibrium composition.
What are 4 things that affect the rate of a reaction?
1. The concentration of the substances. 2. The temperature. 3. The surface area of the particles. 4.The presence of a catalyst.

How does the presence of a hydrogen peroxide catalyst affect the rate of a chemical reaction?
The presence of a hydrogen peroxide catalyst can increase the rate of a chemical reaction by providing an alternative pathway with lower activation energy, allowing the reaction to occur more quickly.
What happens when ethanol and ethanoic acid react in the presence of acid catalyst?
When ethanol and ethanoic acid react in the presence of an acid catalyst, they undergo an esterification reaction to form ethyl ethanoate (ester) and water. This reaction is reversible and reaches equilibrium. The acid catalyst helps to increase the rate of the reaction but does not affect the overall stoichiometry.

How do catalyst and inhibtors affect reaction rate?
A catalyst speeds up the reaction and lowers the amount of heat needed.
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.
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!

How does a catalyst affect the speed of a reaction?
A catalyst enables more particles to reach the activation energy and to take part in the reaction. Therefore the speed of the reaction increases.
Why does catalyst affect reaction speed?
The activation energy is reduced.
