Extracted text: 1) What is Hess's law of constant heat summation? Determine the enthalpy change for the trans formation of (a) sulphur (monochlinc) to sulphur (orthorhombic) (b) sulphur (orthorhombic) to sulphur (monochlinc) from the following chemical equations and data. (3 xl = 3 marks) S (orthorhombic) + O2 (g) → SO2 (g); AH = -297.5 kJ (1) S (тoпоclinic) + O2 (g) > SOz (g); AH = -300.0 kJ (2)
