Question
Given the standard enthalpy changes for the following two reactions:
AH = -325.1 kJ
(1) Sn(s) + Cl2 (g) → SnCl₂ (s)
(2) Sn(s) + 2Cl₂ (g) → SnCl4 (1)
AH = -511.3 kJ
What is the standard enthalpy change for the following reaction?
(3) SnCl₂ (s) + Cl₂(g) → SnCl4 (1)
ΔΗ° =?
Standard enthalpy change =
KJ
