Exo means 'outside' and thermic means 'heat'. When heat is released in a reaction, its called an Exothermic reaction. Now, answering the question, the energy required for the reaction to occur is less than the total energy released. So, the extra energy gets converted into heat or light. So, yes there is a net release of energy in an exothermic reaction.
What else can I help you with?
What is the difference between an exothermic and exergonic reaction in terms of energy release and spontaneity?
An exothermic reaction releases energy in the form of heat, while an exergonic reaction releases energy in the form of free energy. Both reactions are spontaneous, meaning they occur without needing an external energy source.
What type of chemical reaction cannot occurs spontaneously endothermic or exothermic?
An 'exothermic' reaction gives of energy, and an 'endothermic' reaction absorbs energy.
What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
What is an exothermic reaction?
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.
What is the relationship between temperature and the occurrence of an exothermic reaction?
The relationship between temperature and the occurrence of an exothermic reaction is that an increase in temperature typically speeds up the reaction, causing it to occur more quickly. This is because higher temperatures provide more energy for the reaction to proceed, leading to a faster release of heat.
What type of reaction releases energy and does not require initial energy to occur?
All reactions require an activation energy. Some appear not to because that energy is provided enough by their temperature. Thus, there is no reaction that does not require any initial energy to occur. A reaction that results in an overall release of energy is called an exothermic reaction.
What is the difference between an exothermic and exergonic reaction in terms of energy release and spontaneity?
An exothermic reaction releases energy in the form of heat, while an exergonic reaction releases energy in the form of free energy. Both reactions are spontaneous, meaning they occur without needing an external energy source.
What two types of energy change can occur in a chemical reation?
Two types of energy change that can occur in a chemical reaction are endothermic or exothermic. An exothermic reaction causes an increase in temperature and an endothermic reaction causes a decrease in temperature.
What type of chemical reaction cannot occurs spontaneously endothermic or exothermic?
An 'exothermic' reaction gives of energy, and an 'endothermic' reaction absorbs energy.
What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
Are exothermic reactions chemical?
Most chemical reactions are exothermic, that is, they release a certain amount of heat as a by-product of the reaction. Endothermic reactions, those which absorb heat, also do occur, but they are more rare. Endothermic reactions are driven by entropy only, whereas exothermic reactions are driven by the energy that is released. The more energy is released, the more easily the reaction will occur.
What is an exothermic reaction?
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.
Would a catalyst cause an endothermic reaction to become exothermic?
No, a catalyst does not change the overall energy of a reaction. It only lowers the activation energy required for the reaction to occur. Therefore, a catalyst cannot change an endothermic reaction into an exothermic one.
What is the relationship between the temperature and the rate of chemical?
Heat energy is necessary for some chemical reactions to occur. Some chemical reactions are endothermic meaning they require or absorb energy for a chemical reaction to occur. Other chemical reaction are exothermic meaning they release energy when the chemical reaction takes place..
Describe the two types of energy changes that occur in a chemical reaction?
An exothermic reaction and the change between potential and kinetic.
Where do burning wood and coal and fossil fuel get their heat energy from?
When you burn something, you are causing an exothermic reaction to occur. When that heat is released from the reaction, is causes more to burn, keeping the exothermic reaction going.
What is the relationship between temperature and the occurrence of an exothermic reaction?
The relationship between temperature and the occurrence of an exothermic reaction is that an increase in temperature typically speeds up the reaction, causing it to occur more quickly. This is because higher temperatures provide more energy for the reaction to proceed, leading to a faster release of heat.
