DSE Chem revision
Topic 8. Chemical reactions and energy
A. Energy changes in chemical reactions
-
conservation of energy
-
endothermic and exothermic reactions and their relationship to the breaking and forming of bonds
B. Standard enthalpy change of reactions
-
enthalpy change of reaction and standard conditions, with particular reference to neutralisation, solution, formation and combustion
-
carry out experimental determination of enthalpy changes using simple calorimetric method
-
calculate enthalpy changes from experimental results
C. Hess’s law
-
use of Hess’s law to determine enthalpy changes which cannot be easily determined by experiment directly
-
calculations involving enthalpy changes of reactions
