The given gas phase reaction is known as Haber process under conditions of temperature , pressure & concentration. It is based on Lechateliers principle. Through this principle we can predict qualitatively the influence of change in temp, pr or concentration on system in equilibrium.
N2 + 3H2 2NH3
a . When additional N2 is added , the quantity of NH3 has increased , a new equilibrium state is formed & it is shifted to the right.
b . This reaction is reversible reaction & some H2 & N2 remain mixed with the NH3 . The reaction mixture is cooled so that NH3 liquifies & can be removed. So the equilibrium continously shifted to the right.
c . Increasing the pr causes the equilibrium position to move to the right resulting in a higher yield of NH3 since there are more gas molecules on the left than the right.
d . Catalyst affect only the rate of a reaction , they have no effect on the equilibrium state.
Given the gas-phase reaction N_2 + 3H_2 = 2NH_3 Suppose that the action has already taken...
1. The cartoon below represents the reaction of nitrogen gas (N2) with hydrogen gas (H2) to synthesize ammonia (NHs). Industrially, this che pro mical process is called the Haber-Bosch cess, and is still a very important reaction in the manufacture of fertilizers. The ability to fix every day). It has been estimated that use of nitrogen-based fertilizers has doubled the world's a. The cartoon below shows 6 molecules of hydrogen gas and 2 molecules of nitrogen nitrogen and manufacture fertilizers...
What are the instruments that have been utilized for the review article discussions? ` 1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...
