Theromodynamics...

The first law of thermodynamics is only

A mixture of two moles of carbon monoxide and one mole of oxygen, in a closed vessel is ignited to convert the carbon monoxide to carbon dioxide. If ΔH is the enthalpy change and ΔE is the change in internal energy, then 

The relation between ΔE and ΔH is

For the reaction of one mole of zinc dust with one mole of sulphuric acid in a bomb calorimeter, ΔU and w correspond to

For the reaction N₂ + 3H2 ⇌ 2NH3 ; ΔH = 

If ΔH is the change in enthalpy and ΔE the change in internal energy accompanying a gaseous reaction

Hess's law of constant heat summation in based on

Consider the reaction : N₂ + 3H₂ → 2 NH₃ carried out at constant temperature and pressure. If ΔH and ΔU are the enthalpy and internal energy changes for the reaction, which of the following expression is true

Enthalpy for the reaction C + O₂ → CO₂ is
