In a chemical reaction a catalyst changes the 1.potential energy of the products 2.potential energy of the reactants 3. heat of reaction 4.activation energy?
A catalyst lowers the activation energy of a reaction, making it easier for the reactants to form products. It does not change the potential energy of the reactants or products, nor does it affect the overall heat of the reaction.
Assuming that the reaction is at equilibrium what effect does the addition of a catalyst have on the equilibruim?
a catalyst lowers the activation energy for both the forward and reverse reaction. however, it does not change the potential energy of the reactants or products. it also does not affect the heat of reaction (delta h)
What type of catalyst lowers the energy of activation for a reaction?
A catalyst lowers the energy of activation for a reaction by providing an alternative reaction pathway with lower activation energy. This allows the reactants to more easily overcome the energy barrier and proceed to form products at a faster rate.
How can a reaction generally be made to go more quickly?
Lowering the activation energy, Adding a cataylst
What happens to catalyst in a reaction?
it is incorporated into the reactants

Why do catalyst work without adding heat?
A catalyst changes the path of reaction mechanism and decreases the activation energy required by the reactants.
What is the effect of a catalyst on the required energy to acheieve effective collisions?
A catalyst lowers the activation energy of a reaction.
What are the 5 important factors that influence the rate of a chemical reaction?
The key factors that influence the rate of a chemical reaction are concentration of reactants, temperature, presence of a catalyst, surface area of reactants, and the nature of the reactants and products.
What is the difference between a homogeneous catalyst and a heterogeneous catalyst?
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.
What factors influence the activation energy of a chemical reaction?
The factors that influence the activation energy of a chemical reaction include temperature, concentration of reactants, presence of a catalyst, and the nature of the reactants and their bonds.
What type of catalyst lowers the energy of activation for a reaction?
A catalyst lowers the energy of activation for a reaction by providing an alternative reaction pathway with lower activation energy. This allows the reactants to more easily overcome the energy barrier and proceed to form products at a faster rate.
What effect does a catalyst have on a system equilibrium?
The correct answer is a simple one: The system is unaffected by a catalyst in a system in equilibrium.
In a combustion reaction between butane and oxygen which contains more energy reactants catalyst products or products and reactants contain the same amount of energy?
In a combustion reaction between butane and oxygen, the products contain more energy than the reactants. This is because energy is released in the form of heat during the combustion process, increasing the total energy content of the products. The catalyst does not contribute to the overall energy content of the reaction.
What are the reactants of a catalyst-assisted reaction?
Reactants are also known as substrates.
What is the main difference between a heterogeneous catalyst and a homogeneous catalyst?
The heterogeneous catalyst is not mixed with the reactants.
