Developing Fuels
Enthalpy Change
ΔH = Hproducts - Hreactants
ΔH affected by temp, pressure and conc of solutions
Energy Transferred = specific heat capacity x mass x temperature change
ΔH = H products - Hreactants
Enthalpy of combustion = follow arrows down
Enthalpy of formation = first arrow down, last arrow up
Enthalpy of neutraslisation = follow arrows up
Compounds that don't contain a benzene ring are called aliphatic compounds
Alkenes are saturated hydrocarbons
Cracking describes any reaction which a larger molecule is made into smaller molecules.
An addition reaction is one where two or more molecules react to form a single, larger molecule.
Alkanes produce two branched alkanes
Alkanes produce smaller alkane(s) and cycloalkanes
Cycloalkanes produce alkanes and branched alkanes
Alkenes produce smaller alkenes
Electrophilic Addition Reactions
Reaction with bromine
Reaction with hydrogen bromide
Reaction with water
Reaction with hydrogen
PV = nRT
Pressure (Pa) x Volume (m3) = amount of gas (moles) x gas constant R (JK-1mol-1) x temperature (k)
