Bond energy is the energy WHAT or the energy WHAT
Bond energy is the energy REQUIRED to BREAK a CHEMICAL BOND or the energy RELEASE when a BOND is FORMED
The WHAT of a reaction represents the WHAT from WHAT the bonds in the reactants and WHAT the bonds of the products
The CHANGE in ENTHALPY of a reaction represents the NET EFFECT from BREAKING the bonds in the reactants and FORMING the bonds of the products
In exothermic reactions, bonds breaking absorbs WHAT energy than the bond formation gives off, resulting in a WHAT
In exothermic reactions, bonds breaking absorbs LESS energy than the bond formation gives off, resulting in a -ΔH
In endothermic reactions bond breaking absorbs WHAT energy than the bond formation gives off, resulting in a WHAT
In endothermic reactions bond breaking absorbs MORE energy than the bond formation gives off, resulting in a +ΔH
Bond breaking = WHAT energy
ADDING energy
Bond forming = WHAT energy
RELEASING energy
The energy barrier that must be overcome for a chemical reaction to occur is called the WHAT
ACTIVATION ENERGY
Examples of activation energy include:
An IGNITION source (burning match, a spark, electricity)
The atoms in the WHAT have to be WHAT in order for them to bond in a different WHAT and become WHAT
The atoms in the REACTANTS have to be “PULLED APART” in order for them to bond in a different CONFIGURATION and become PRODUCTS
The activation energy is always WHAT than the energy contained in the reactants and the products, however the amount of activation energy is dependent on the reaction
HIGHER
Collision Theory:
Particles must collide with
The proper WHAT
Sufficient WHAT
Collision Theory:
Particles must collide with
The proper ORIENTATION of MOLECULES
Sufficient COLLISION ENERGY
