Question

N2 + 3 H2 gives to 2NH3 + heat what can be concluded from the API action​

Answer 1

Answer:

From the given reaction it can be concluded that the given reaction is an example of synthesis and exothermic reaction.

Explanation:

The reaction given is as follows:

$N_2+H_2\rightarrow 2NH_3+ Heat$

When the reaction is examined, the two reactants are combining to the formation of one product.

Thus the reaction is an example of synthesis or combination reaction.

On the other hand, heat is produced in the form of energy which indicates that the given reaction is also exothermic.

Thus the conclusion drawn from the given reaction is that it is an exothermic and combination reaction.

Answer 2

Effect of temperature: According to Le Chatelier principle,  the equilibrium will move in such a way as to counteract the change, so, on increasing the temperature: 1) If the reaction is exothermic (heat is relesing during reaction), then rate of reaction decreases, so reaction proceeds in backward direction. If the reaction is endothermic (ie heat is absorbing during reaction), then rate of reaction increases, so reaction proceeds in forward direction.Effect of pressure: According to Le Chatelier principle, on increasing the pressure, the equilibrium will move in such a way as to counteract the change i.e. the position of equilibrium will move in such a way that the pressure is reduced again. The more molecules present, the higher the pressure will be. Therefore system can reduce the pressure by reacting in a way to produce fewer molecules.number of gaseous molecules in reactant side : 1 + 3 = 4number of gaseous molecules in product side : 2so, on increases pressure, reactant molecules will feel more pressure due to which reaction will proceed in forward direction so as to reduce the pressure on reactant molecules.
