What is the minimum energy required for molecules to react with each other called?
That is called the activation energy or energy of activation (Ea).
What is the first thing that must occur for two molecules to react with one another?
The two molecules must collide with the correct orientation and with a minimum amount of energy (called the activation energy).
Which molecules are essentially required to absorb solar energy to carry out photosynthesis?
Which molecules are essentially required to absorb solar energy to carry out photosynthesis?
What is it called when heat energy required to break up the attraction of liquid molecules?
When liquid molecules absorb enough heat energy, evaporation occurs.
Is more energy used to melt ice or freeze water?
The energy required is the same. It is the energy required to rearrange the molecules from one state to another.
What is the minimum energy required for molecules to react with each other called?
That is called the activation energy or energy of activation (Ea).
What is force energy?
The minimum energy required for molecules to react.
What is the first thing that must occur for two molecules to react with one another?
The two molecules must collide with the correct orientation and with a minimum amount of energy (called the activation energy).
What is the minimum amounth of energy required for a reaction occur?
The minimum amount of energy needed for a reaction to take place is called the activation energy.
What is the minimum amount of energy required for two substances to react?
The minimum amount of energy needed is called the "activiation energy". It varries depending on factors such as your reaction, temperature and several others.
Which molecules are essentially required to absorb solar energy to carry out photosynthesis?
Which molecules are essentially required to absorb solar energy to carry out photosynthesis?
What is it called when heat energy required to break up the attraction of liquid molecules?
When liquid molecules absorb enough heat energy, evaporation occurs.
What is energy is a minimum amount of energy required for substances to react?
Activation Energy
Activation energy is the minimum energy required to do what?
For the substance(s) to react
The amount of energy required to start a reaction is called?
Activation energy. Pg 112 of the living world by Johnson and losos
Difference between threshold energy and activation energy?
THRESHOLD ENERGY(T.E) You consider any particular reaction. the molecules of the reactants must necessarily possess certain minimum value of kinetic energy for the collision with other reactant and to from product . this minimum energy that the reactant molecules should possess is known as threshold energy (T.E) ACTIVATION ENERGY (A.E) Do you think all the molecules will possess this particular minimum kinetic energy required to form products? obviously not. if you take the graph of no of molecules vs their kinetic energy graph, you will see that only few molecules possess this minimum kinetic energy. so for other molecules also to participate in the reaction you need to provide certain extra energy to them by some means which is known as the activation energy. (A.E) Now the question arises ,how to calculate the activation energy. suppose in a reaction the average kinetic energy of the molecules of reactant be 10Joules , threshold energy is 50Joules. so what energy should be supplied for all the molecules to react. this is nothing but T.E - Average kinetic energy i.e.,50-10=40Joules. this is what is known as activation energy so ACTIVATION ENERGY (A.E) THRESHOLD ENERGY (T.E) AND AVERAGE KINETIC ENERGY (K.E) ARE RELATED AS A.E=T.E - K.E
Which statement defines activation energy?
Activation energy is defined as the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction. That means the energy required to activate atoms or molecules.
