Which is a best definition of activation energy?
Activation energy is energy or power conducted that can be instantly activated for use when flick a light switch you used activation energy.
What are three sources of activation energy?
Heat: Increasing the temperature of a reaction provides molecules with more kinetic energy, enabling them to overcome the activation energy barrier. Catalysts: Catalysts lower the activation energy required for a reaction, speeding up the rate of the reaction without being consumed themselves. Light: Photons can provide energy to molecules, allowing them to reach the activation energy required for the reaction.
The initial activation energy for the process of photosynthesis is?
The initial activation energy for the process of photosynthesis is the energy required to initiate the conversion of light energy into chemical energy. This energy is used to break the bonds in the reactants and start the photosynthetic reactions.
What is the relationship between temperature and the activation energy on a graph?
On a graph, the relationship between temperature and activation energy is typically shown as an inverse relationship. As temperature increases, the activation energy required for a reaction decreases. This is because higher temperatures provide more energy to molecules, making it easier for them to overcome the activation energy barrier and react.
What is it called when energy is required to start a chemical reaction?
An exergonic reaction is activation energy (or energy of activation). An endergonic reaction is essentially the opposite of an exergonic reaction.
When you strike a match what do you provide that enables the flame to appear?
D) activation energy
Why does fruit not provide light energy?
Fruit does not provide light energy because it is not a source of light, it does not generate light and glow.
How enzymes works?
Provide an alternate pathway with a lower activation energy for a reaction
What is the minimum amount of energy needed to start a chemical reaction?
The minimum amount of energy needed to start a chemical reaction is called the activation energy. It is the energy required to break the bonds in reactant molecules and initiate the reaction. Once this energy barrier is overcome, the reaction proceeds without additional energy input.
Is it true that another way to control the rate of a reaction is to change the activation energy needed?
Yes, altering the activation energy required for a reaction can impact the reaction rate. Lowering the activation energy makes it easier for the reaction to occur, speeding up the rate, while increasing the activation energy slows down the rate. This is often achieved by using catalysts to provide an alternative reaction pathway with lower 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.
Energy needed to kick start a reaction is called what?
The energy needed to kick start a reaction is called activation energy. It is the minimum amount of energy required for a chemical reaction to occur. It is usually provided in the form of heat or light energy.
