Stability of Products V. Reactants
if products have higher energy = endothermic
If reactants have higher energy= exothermic
If Delta H is negative is negative
rxn is exothermic
If Delta H is positive
rxn is endothermic
Enthalpy
measure of heat of reaction
Heat of Rxn
amount of energy gained or lost during a chemical equation
Specific Heaat
amount of energy needed to raise 1g of sample 1 degree celcius
Heat depends upon
speed, number, and type of particles
Heat
measure of the TOTAL Kinetic energy of sample
Temperature
mease of average KE of sample
Calorimeter
instrument used to measure heat changes
