Enthalpy and Relation Between delta H & delta U

Write the mathematical relation between Delta H and Delta U during formation of one mole of CO_2 under standard conditions.

Derive the relationship between Delta H " and " Delta U for an ideal gas. Explain each term involved in the equation.

The enthalpy of reaction, Delta_(1) H , is

Assertion: A dynamic equilibrium means a balance between the tendency towards minimum and mazimum ethalpies. Reason: The reaction having Delta H = -ve occurs form high ethalpy side to low enthalpy side and the reaction Delta H = +ve occurs form low enthalpy side to high enthalpy side.
