0.00595mal 3 0948 22322- UL 2. ole 11284) Calculate the standard enthalpy of the reaction Hz(g) + Cl2(g) → 2HCl(g) Given: CoC

Answer 1

Answer #1

4)

Lets number the reaction as 0, 1, 2, 3 from top to bottom

required reaction should be written in terms of other reaction

This is Hess Law

required reaction can be written as:

reaction 0 = -0.5 * (reaction 1) -0.5 * (reaction 2) -0.25 * (reaction 3)

So, ΔHo rxn for required reaction will be:

ΔHo rxn = -0.5 * ΔHo rxn(reaction 1) -0.5 * ΔHo rxn(reaction 2) -0.25 * ΔHo rxn(reaction 3)

= -0.5 * (47.5) -0.5 * (210.0) -0.25 * (-805.0)

= 72.5 KJ

Answer: 72.5 KJ
