6.2 How Is Energy Transformed During Chemical Reactions?

Activation energy
1. Activation energy, the energy required to a star in a chemical reaction. Every push.
2. Activation energy is the energy required to overcome the repulsive forces between the electron shells so that they can move close enough together to react.
Chemical reactions
1. A chemical reaction is a process that forms or breaks the chemical bonds that holds atoms together.
2. Chemical reactions convert one set of chemical substances, the reactants, into another set, the products.
3. All chemical reactions either release energy or require an overall (net) input of energy.
Exergonic
1. Exergonic reactions release energy and absorb energy from the surrounding. All exergonic reactions release some of their energy as heat
2. Exergonic reactions are known as running downhill, from higher to lower energy,
Endergonic
1. A reaction is endergonic if it requires a net input of energy; that is if the products contain more energy than the reactants.
2. Synthesizing complex biological molecules requires a net input of energy. Endergonic
3. Endergonic reactions also known as uphill reactions (reactants contains less energy than the products).
