Enthalpy of Reaction Worksheet + Solutions 
Build confidence with calculating enthalpy changes using standard enthalpies of formation with this completely FREE worksheet and answer sheet.
 
Students practise using:
ΔH°reaction = ΣΔH°f(products) − ΣΔH°f(reactants)
The resource includes a worked example, 12 calculation questions across a range of reactions, and a full answer sheet with calculations shown. It also reinforces the key rule that the standard enthalpy of formation of an element in its standard state is zero.  
 
Ideal for Leaving Certificate Chemistry, class practice, homework or revision.
Includes:
✓ Worked example
✓ 12 practice questions
✓ Full worked solutions
✓ Printable PDF
✓ FREE download
