Interpretation:
For combustion of methane to carbon dioxide and liquid water the
Concept Introduction:
Energy of Combustion: The energy released in the form of heat when given substance undergoes combustion reaction.
Entropy change: The sign of
- When a molecule is broken down and gives two or more smaller molecules.
- When the moles of gas is increases (by the breaking of molecules)
Solid changes to liquid or gas state or liquid state changes to gas state.
Entropy
If the disorder increases in a system, then
If the disorder decreases in a system, then
If the disorder equal in a system, then
Entropy is the measure of randomness in the system. Standard entropy change in a reaction is the difference in entropy of the products and reactants.
