What type of chemical reaction cannot occurs spontaneously endothermic or exothermic?
An 'exothermic' reaction gives of energy, and an 'endothermic' reaction absorbs energy.
Chemical changes release energy?
Chemical changes can either absorb or release energy. When a chemical reaction releases energy, it is called an exothermic reaction. This means that the products of the reaction have lower energy than the reactants, and the excess energy is released in the form of heat or light.
The expositon of dynamite is a chemical reactiondoes this reaction absorb or release energy?
Exothermic reactions release energy. Endothermic reactions absorb energy.
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..
What conditions are necessary for an energetically favorable reaction to occur?
For an energetically favorable reaction to occur, the reactants must have lower energy than the products, and the reaction must release energy rather than absorb it. This is known as having a negative change in free energy (G) for the reaction to proceed spontaneously.
A chemical reaction that releases energy is called?
Exothermic reactions
Can chemical reactions absorb energy?
Yes, chemical reactions can absorb energy. This can occur in endothermic reactions, where energy is required for the reaction to proceed. Examples include the reaction of baking soda and vinegar, which absorbs heat energy.
Which type of chemical reaction needs to absorb energy to proceed?
endothermic
What is the difference between a reaction that happens spontaneously and a reaction that doesn't?
The difference can be clarified by entropy (the second rule of thermodynamics).The reaction is more spontaneous with higher entropy, for the reactions that occur spontaneously the entropy is higher than for the ones that do not.
What must be absorb before a chemical reaction can start by the reactants?
energy
What is the relative amount of energy released in chemical reactions?
The relative amount of energy released in chemical reactions varies depending on the specific reaction. Some reactions release a lot of energy, while others release less or even absorb energy. This energy release or absorption is known as the reaction's enthalpy change.
Is it true that Every chemical reaction gives off energy?
yes it does <><><> No- some reactions ABSORB energy. In terms of heat energy, some are exothermic, and some are endothermic.
