Titanium metal is extensively used in aerospace industry because the metal imparts strength to structures but does not unduly add to their masses. The metal is produced by the reduction of $$TiCl4(l)$$ which in turn is produced from mineral rutile $$TiO2(s)$$. The following reaction for production of $$TiCl4$$⁡$$($$ℓ$$)$$ be carried out at $$25$$∘C:$$TiO2(s)+2Cl2(g)$$⟶$$TiCl4($$ℓ$$)+O2(g)$$. Given that Δ$$Hf0$$ for $$TiO2(s)$$,$$TiCl4$$⁡$$($$ℓ$$)$$,$$Cl2(g)$$ and $$O2(g)$$ is −$$944.7$$,−$$804.2$$,$$0.0$$,$$0.0KJmol$$−$$1$$⋅S∘ respectively for $$TiO2(s)$$,$$TiCl4($$ℓ$$)$$,$$Cl2(g)$$ and $$O2(g)$$ is $$50.3$$,$$252.3$$,$$233.0$$,$$205.1Jmol$$−$$1K$$−$$1$$ respectively.

Question

Titanium metal is extensively used in aerospace industry because the metal imparts strength to structures but does not unduly add to their masses. The metal is produced by the reduction of $$TiCl4(l)$$ which in turn is produced from mineral rutile $$TiO2(s)$$. The following reaction for production of $$TiCl4$$⁡$$($$ℓ$$)$$ be carried out at $$25$$∘C:$$TiO2(s)+2Cl2(g)$$⟶$$TiCl4($$ℓ$$)+O2(g)$$. Given that Δ$$Hf0$$ for $$TiO2(s)$$,$$TiCl4$$⁡$$($$ℓ$$)$$,$$Cl2(g)$$ and $$O2(g)$$ is −$$944.7$$,−$$804.2$$,$$0.0$$,$$0.0KJmol$$−$$1$$⋅S∘  respectively for $$TiO2(s)$$,$$TiCl4($$ℓ$$)$$,$$Cl2(g)$$ and $$O2(g)$$ is $$50.3$$,$$252.3$$,$$233.0$$,$$205.1Jmol$$−$$1K$$−$$1$$ respectively.
