What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What is the The energy required to start an enzymatic reaction?
The energy required to start an enzymatic reaction is called the activation energy. It is the energy needed to initiate the chemical reaction that the enzyme facilitates. Enzymes lower the activation energy required for a reaction to occur, making it easier and faster for the reaction to take place.
The smallest amount of energy needed to start a chemical reaction is called?
Technically, it isn't "heat" that makes a chemical reaction happen. "Heat" is merely the flow of energy from one place to another. It is the energy itself that causes a reaction to occur. As an increase in temperature occurs, there is an increase in the energy in a group of molecules by making them mover around faster and bum into each other more. This energy is called "Activation energy", and is defined as the amount of energy required to make the reaction start and carry on spontaneously. Higher activation energy implies that the reactants need more energy to start than a reaction with a lower activation energy. With that being said, activation energy is the answer
Which is the best description of activation energy?
The amount of energy needed to start a chemical reaction. Source: Biology class
Is more energy required for a chemical reaction in the absence of an enzyme?
Without an enzyme, the activation energy needed to start a reaction is much greater. An enzyme is a catalyst, which decreases the amount of activation energy needed to start a reaction. By doing so, it decreases the amount of time the chemical reaction takes place.
What do chemist call the energy needed to start a reaction?
The energy needed to start a chemical reaction is called the activation energy :)
What effect does an enzyme have on a activation energy needed to start a reaction?
In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
The minimum amount of energy needed to start a chemical reaction is called?
The activation energy.
Is the amount of energy needed to cause a chemical reaction to start called activation energy?
yes
What is proteins that reduce the amount of energy needed to start a chemical reaction are called?
Proteins that reduce the amount of energy needed to start a chemical reaction are called enzymes. Enzymes act as catalysts by lowering the activation energy required for a reaction to occur, thus speeding up the reaction.
The energy necessary to start a chemical reaction?
The energy required to start a chemical reaction is called activation energy. It is the minimum amount of energy needed to initiate a reaction by breaking the chemical bonds of the reactants. This energy barrier must be overcome for the reaction to proceed.
What energy is the energy needed to start a reaction?
Activation Energy.
The minimum amount of energy needed to start any reaction?
The minimum amount of energy needed to start a reaction is called the activation energy. It is required to break the bonds in reactant molecules and initiate the process of forming new bonds in the products. This energy barrier must be overcome for a chemical reaction to occur.
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What is the The energy required to start an enzymatic reaction?
The energy required to start an enzymatic reaction is called the activation energy. It is the energy needed to initiate the chemical reaction that the enzyme facilitates. Enzymes lower the activation energy required for a reaction to occur, making it easier and faster for the reaction to take place.
The amount of energy needed to start a chemical reaction is called what?
The energy required is called the activation energy. The minimum amount of energy needed to start a chemical reaction is given by the formula Ea=-RT*ln(k/A). R is the universal gas constant, T is temperature in Kelvin, k is the reaction rate coefficient and A is the frequency factor.
What do chemists call the energy needed to get a reaction started?
Chemists call the energy needed to get a reaction started the activation energy. This energy is required to break the bonds of the reactant molecules before they can form new bonds and produce products.
