Based on the assumption that the reaction involves N and O to produce NO, if 25.0 g of NO are produced, the amount of N gas used would be 11.66 grams

<h3>Stoichiometric calculation</h3>

From the equation of the reaction:

N + O ---------> NO

Mole ratio of N to NO is 1:1

Mole of 25.0 g of NO = 25/30.01 = 0.833 moles

Equivalent mole of N = 0.833 moles

Mass of 0.833 moles N = 0.833 x 14 = 11.66 grams

Use LeChâtelier's principle explain why the concentration of NO at equilibrium increases when the reacuon takes place at higher

Tatiana [17]

increasing the temperature shifts the equilibrium in the direction of the reaction in which heat is absorbed.

Explanation:

The concentration of NO at equilibrium will increase when the reaction takes place at a higher temperature because increasing the temperature shifts the equilibrium in the direction of the reaction in which heat is absorbed.

The reaction is an endothermic reaction.

N₂ + O₂ + heat ⇄ 2NO

According to Le Chatelier's principle, "if any of the conditions of a system in equilibrium is changed the system will adjust itself in order to annul the effect of the change".

In an endothermic reaction, heat is usually absorbed.
We see that in the backward reaction, heat is absorbed.
If the temperature of this reaction is increased, the backward reaction is favored more.
Since the reactants are combining better, more products NO results.
