Reactions involving two phases proceed more rapidly when there is greater surface area contact. If temperature or reactant concentration is increased, the rate of a given reaction generally increases as well. A catalyst can increase the rate of a reaction by providing an alternative pathway that causes the activation energy of the reaction to decrease.

The direction of shift can be predicted for changes in concentrations, temperature, or pressure. Catalysts do not affect the position of an equilibrium; they help reactions achieve equilibrium faster.

It highlights the contributions of Karl Bosch and Fritz Haber, along with operational parameters like high pressure and intermediate temperatures. The process utilizes a catalyst and focuses on maximizing ammonia yield through recycling unreacted gases. Ongoing research aims to enhance catalysts and further comprehend the reaction's energetics.

It was isolated in 1867 by Henry Roscoe as a silvery-white metal that is somewhat heavier than aluminum but lighter than iron. It has excellent corrosion resistance at room temperature.

Reactants may also be present in such low concentrations that it is unlikely they will meet and collide. Therefore, the rate of most biochemical reactions must be increased by a catalyst, which speeds up chemical reactions. In organisms, catalysts are called enzymes.
