Mr. Knight still can't find some of his enthalpy values. The last equation on his list is this: CHC130) + 3HCl(g) → CH4(g) + 3Cl2(g) Calculate the enthalpy value for this reaction using the following equations [4 marks]: 1 i. H2(g) + Cl2(g) → HCl(g) AH= -92.3 kJ ii. C(s) + 2H2(g) → CH4(g) AH= -74.8 kJ iii. C(s)+ H2(g) + Cl2 CHCl30) AH°= -134.5 kJ 2 Mr. Knight still can't find some of his enthalpy values.
