question

Your supervisor asks you to determine the enthalpy of a certain chemical reaction. Which would you do?

choices

  1. Measure the ΔS and the ΔG for the reaction, and calculate the ΔH from the Gibbs free energy equation.
  2. Use a bomb calorimeter to measure the heat of the reaction.
  3. Use a solution calorimeter such as a coffee-cup calorimeter to measure the heat.
  4. Use a photoelectron spectrometer to measure the energies of all atoms in the compounds, and use Hess's law to add them.
