WebAn experiment is done to determine the enthalpy of combustion of a fuel using a calorimeter containing water. b = mass of fuel burned / g w = mass of water heated / g Δ T = temperature rise of water / K M r = relative molecular mass of fuel c = specific heat capacity of water / J K − 1 g − 1 Which expression gives the enthalpy of combustion (in J m o l … WebProblems in relating the sign of the enthalpy change to solubility. The table above illustrates this problem, but it gets worse! Taking the sign of enthalpy of solution at face value, you get some bizarre results.
