To find ∆H for the reaction with the equilibrium constant 0.65 at 755 K. Concept introduction: ► The equilibrium constant is defined as a ratio of the concentration of the products to the concentration of the reactants. If the K value is less than one the reaction will move to the left and if the K value is greater than one the reaction will move to the right. ► Enthalpy change is the name given to the amount of heat evolved or absorbed in a reaction carried out at constant pressure. It is given the symbol ΔH, read as "∆H". The term "enthalpy change" only applies to reactions done at constant pressure. To determine: T h e e n t h a l p y ( Δ H r x n 0 ) f o r a r e a c t i o n .

Concept introduction:
► The equilibrium constant is defined as a ratio of the concentration of the products to the concentration of the reactants. If the K value is less than one the reaction will move to the left and if the K value is greater than one the reaction will move to the right.
► Enthalpy change is the name given to the amount of heat evolved or absorbed in a reaction carried out at constant pressure. It is given the symbol ΔH, read as "∆H". The term "enthalpy change" only applies to reactions done at constant pressure.
