The standard enthalpy of formation of SnCl₂ (s) is - 340 kJ/mol and that for SnCl4 (s) is-511 kJ/mol. From these data, we can calculate that for the reaction SnCl₂ (s) + Cl₂ (g) →→SnCl4 (s), the value of AH O cannot be determined as AH, for Cl₂ (g) is not given. O equals - 851 kJ. O equals + 171 kJ. O equals - 171 kJ.
