A solution was made by dissolving a spatula of potassium nitrate into 50 cm 3 of water. The temperature changed from 20.4˚C to 18.7˚C. Calculate the enthalpy change for this reaction. To calculate the ...

Hess’s Law states that the enthalpy change for a chemical reaction is independent of the route taken. This means that the enthalpy change for the overall process will be identical regardless of how ...
