For a reversible reaction, the equation of which is N2 + 3H2HN3 + Q

For a reversible reaction, the equation of which is N2 + 3H2HN3 + Q Specify the conditions that cause a shift in chemical equilibrium towards the reaction product.

According to Le Chatelier’s principle, when acting on the system, the chemical equilibrium shifts in the direction that compensates for this effect. In the case of an ammonia synthesis reaction:

1) The process is exothermic, which means that a decrease in temperature will lead to an increase in product yield;

2) The process goes with a decrease in the amount of gaseous substances, which means that an increase in pressure will also lead to an increase in the yield of the product.

3) An increase in the concentration of reagents will shift the equilibrium towards the formation of ammonia.

Important! The addition of a catalyst has practically no effect on the chemical equilibrium.
