Reversible reactions and equilibria

Understand that chemical reactions can be reversible, recognize the standard symbol for reversibility, and explain how altering reaction conditions can shift the direction of a reversible reaction.

Explain the concept and characteristics of a dynamic equilibrium in a chemical system.

Describe the synthesis of ammonia as a reversible reaction between nitrogen and hydrogen that is capable of reaching dynamic equilibrium.

Recall the specific optimal conditions required for the Haber process: a temperature of 450 °C, a pressure of 200 atmospheres, and the presence of an iron catalyst.

Predict how changes in temperature, pressure, and concentration will affect the position of a dynamic equilibrium.
