Given the equation representing a chemical reaction at equilibrium in a sealed, rigid container:when the concentration of h2(g)
MrRa [10]

Answer:

The equilibrium shifts to the right, shifting towards the products, thereby favouring forward reaction, leading to the production of more product (NH₃) and a reduction in the rate of backward reaction, resulting in a decrease in the production of reactant N₂ in the reaction.

Explanation:

Complete Question

Given the equation representing a chemical reaction at equilibrium in a sealed, rigid container:

N₂ (g) + H₂ (g) ⇌ NH₃ (g)

When the concentration of H₂(g) is increased by adding more hydrogen gas to the container at constant temperature, the equilibrium shifts

Solution

Le Chatelier's Principle explains the behaviour of the equilibrium in response to disturbances in properties for chemical reactions.

The principle states that, if the concentration, temperature and/or pressure of a chemical reaction at equilibrium is changed, the equilibrium position shifts to remedy this changes.

So, for a chemical reaction at equilibrium, provided that the other factors such as temperature and pressure remain constant, if more reactants are added (more H₂ is pumped into the reacting container), the equilibrium responds by shifting to the right, shifting towards the products, thereby favouring forward reaction, leading to the production of more product (NH₃) and a reduction in the rate of backward reaction, resulting in a decrease in the production of reactant N₂ in the reaction.

Hope this Helps!!!

What is emitted when an electron returns to its lower energy level?
Yakvenalex [24]

Answer:

When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
