(a)

Interpretation Introduction

Interpretation:

The standard energy of formation ΔUf0 for K2O needs to be calculated based on the given conditions which involves the combustion of a known mass of K in a constant volume calorimeter

Concept Introduction:

  • Combustion is a thermochemical reaction in which a substance burns in the presence of excess oxygen to produce carbon dioxide and water.
  • Combustion reactions are exothermic in nature i.e. it is accompanied by the release of energy.

(b)

Interpretation Introduction

Interpretation:

The standard enthalpy of formation ΔHf0 for K2O needs to be calculated based on the given conditions which involves the combustion of a known mass of K in a constant volume calorimeter

Concept Introduction:

For a given chemical reaction, the enthalpy change ΔH can be related to the change in internal energy ΔU as:

  ΔH = ΔU+ΔnRT  ---(2)where Δn = change in the number of moles                = n(products)- n(reactants)
