How will this system at equilibrium be affected by each of the conditions stated here?

Factors affecting a system in equilibrium are;

Explanation:

A chemical equilibrium occurs when there is a proportion in mixtures of reactants and products.

For concentration, where some of the reactants are removed from an equilibrium reaction, the contents in the product side will be unbalanced thus the system will not be  equilibrium and according to the Le Chatelier's principle, a system will shift in a manner to return balance in the reaction.

In temperature, in endothermic reactions, energy is considered as a reactant where as in exothermic reactions, energy is considered as a product.In exothermic reactions increase in temperature increases the reaction causing unbalanced reaction. A decrease in temperature causes a backward reaction which is endothermic

Increase in pressure causes the equilibrium to shift to the side of reaction with fewer moles of the reacting gas, where as a decrease in pressure forces the equilibrium to shift to the side of reaction with more moles of gas.
