What is the amount that must be absorbed to start the reaction called?
The amount that must be absorbed to start a reaction is called the activation energy. This energy barrier needs to be overcome for reactants to transform into products, allowing the reaction to proceed. It is essential in determining the rate of the reaction and varies for different chemical processes.
What must energy do to break achemical bonds for a reaction to occur?
Energy must be absorbed to break chemical bonds for a reaction to occur. This energy input is needed to overcome the bond's stability and allow new bonds to form in the reaction.
What must be absorb before a chemical reaction can start by the reactants?
energy
Enzymes work by lowering the what?
Also known as activation energy. threshold energy or you can also say enzymes lower the energy barrier
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
What must be equal to the amount of sunlight reflected plus the amout absorbed?
The amount of sunlight reflected plus the amount absorbed must be equal to the amount of sunlight that hits the surface (incident sunlight) in order to account for all the incoming solar radiation.
In calculating the heat given off by a reaction in a calorimeter you must account for heat absorbed by?
In calculating the heat given off by a reaction in a calorimeter, you must account for heat absorbed by the surroundings, including the calorimeter itself, any water or solution in the calorimeter, and the air around the calorimeter that may be affected by the reaction. This ensures an accurate measurement of the heat released or absorbed by the reaction itself.
The heat of fusion for water is the amount of energy that must be absorbed for water to what?
Melt.
What must be added to a reactant to start a chemical reaction?
Either an energy source to start the reaction or a catalyst.
What is required for a chain reaction to start?
For a chain reaction to start, there needs to be a sufficient amount of fissile material, such as uranium-235 or plutonium-239, present in a compact enough form to reach critical mass. Additionally, there must be a neutron source to initiate the reaction by introducing a neutron to the fissile material.
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.
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 must energy do to break achemical bonds for a reaction to occur?
Energy must be absorbed to break chemical bonds for a reaction to occur. This energy input is needed to overcome the bond's stability and allow new bonds to form in the reaction.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
What must be absorb before a chemical reaction can start by the reactants?
energy
What is a good sentence for activation energy?
Activation energy is the minimum amount of energy that must be provided to start a chemical reaction.
If heat must be added to a chemical reaction for the reaction to take place the reaction is?
Endothermic reactions need heat. Exothermic reactions give off heat.
