What else can I help you with?
Complete the sentence when an enzyme affects a chemical rection it is acting as a biological?
catalyst. An enzyme speeds up the rate of a chemical reaction by lowering the activation energy required for the reaction to occur. This allows the reaction to happen more quickly and efficiently within biological systems.
Which would have the lowest activation energy?
Activation energy is just the energy needed to start a reaction, so it is not clear which has the lowest. Some reactions have negative reaction energy, which is just equivalent to a barrierless reaction.
What factor will most likely lower the activation energy of a reaction?
The presence of a catalyst is most likely to lower the activation energy of a reaction by providing an alternative pathway for the reaction to occur. Catalysts work by stabilizing the transition state, making it easier for the reaction to proceed.
What do catalysts do to the activation energy of a chemical reaction?
A chemical catalyst is a substance that lowers the required activation energy of a reaction. The activation energy is the amount of energy required to "activate" or start a process, this can be in the form of many things, such as heat. A chemical catalyst can be seen as a kind of shortcut in a chemical process to speed things up. A catalyst can also be used to increase the activation energy, so that the reaction will slow down. This is useful for slowing down reactions that are normally too fast to witness.
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).
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 is activation energy How does a catalyst affect activation energy?
Activation energy is the energy required by a reaction for the reaction to occur. The catalyst lowers the activation energy, making it easier for the reaction to happen.Improvement:A catalyst don't lowers the activation energy. A catalyst creates a alternative route (*) for the same reaction with a lower activation energy.* = as a result of the interaction of the reagents with the catalyst.
What type of protein acts as a biological catalyst lowering the activation energy of a reaction?
Enzymes
What is the activation energy needed for a chemical reaction decreased by?
The activation energy is decreased by a catalyst.
How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
How does the catalyst affects the activation energy of a chemical reaction?
catalyst will generally reduce the activation energy
What increases the rate of a reaction by lowering the activation energy?
A catalyst can increase the rate of a reaction by lowering the activation energy needed for the reaction to occur. Catalysts provide an alternative reaction pathway with a lower activation energy, allowing the reaction to happen more quickly.
How does catalyst affect the activation energy of chemical reaction?
The presence of a catalyst affects the activation energy of a reaction by lowering the activation energy, helping the reaction go faster and making it so the reaction does not have to use as much energy to fulfill the products.
Why do you need a catalyst during a enzyme reaction?
A catalyst speeds up the rate of a chemical reaction by lowering the activation energy needed for the reaction to occur. In the case of an enzyme-catalyzed reaction, the enzyme serves as a biological catalyst, allowing the reaction to occur more efficiently and at lower energy levels than it would without the enzyme.
What can alter the activation energy if a reaction?
A catalyst alter rate of reaction by lowering the activation
What is the biological equivalent of catalyst?
An enzyme is the biological equivalent of a catalyst.
What activation energy is needed for a chemical reaction is decreased by?
The activation energy is decreased by a catalyst.
