1. Define each of the following for a chemical reaction: Favored Non-favored Exothermic Endothermic AH AE

Consider the relative energy diagrams for four different processes: Potential energy A Reaction coordinate Potential energy B Reaction coordinate Potential energy Reaction coordinate Compare energy diagrams A and B. Which process will more greatly favor products at equilibrium? Explain. Process B more greatly favors products at equilibrium because it has a lower energy of activation. Potential energy Process A more greatly favors products at equilibrium because it has a higher energy of activation. Process A more greatly favors products at equilibrium because it is exergonic. Process B more greatly favors products at equilibrium because it is endergonic. D Reaction coordinate

Ammonia is made from nitrogen and hydrogen. The enthalpy change in the reaction is -92 kJ/mole. The reaction is reversible and reaches equilibrium   Write the equation for the reaction
