Answer 26

Explanation of Solution

The balanced equation for the given reaction follows as,

SF6(g) + 3 H2O(l) → 6 HF(g) + SO3(g)

Standard enthalpy of formation values is given below,

ΔHfo of SF6(g) =− 1209 kJ/molΔHfo of H2O(l) = −285.83 kJ/molΔHfo of HF(g) = −271.1 kJ/molΔHfo of SO3(g) = −395.72 kJ/mol

Change in enthalpy can be calculated by the equation:

ΔHrxn∘=∑npΔHfο(products) −∑nrΔHfο(reactants)

Substitute the values as follows,

ΔHrxno = [(6 mol×−271.1 kJ/mol) + (1 mol×−395.72 kJ/mol)] − [(1 mol×− 1209 kJ/mol) + (3 mol×−285.83 kJ/mol) ] = 44.17 kJ
