Answer 1

химическое равновесие переместится в противоположную сторону реакции, если увеличить температуру

Answer 2

Chemical Equilibrium Shift

When considering the reaction N2 + O2 ⇌ 2NO, the direction of the chemical equilibrium can be influenced by several factors.

a) Increase in Temperature - Increasing the temperature will shift the equilibrium in the endothermic direction, favoring the formation of NO. This is because the reaction is endothermic, meaning it absorbs heat. As a result, increasing the temperature will favor the reaction that absorbs heat, leading to the formation of more NO.

b) Increase in Pressure - The reaction involves the same number of moles of gas on both sides, so changing the pressure will not shift the equilibrium in either direction. According to Le Chatelier's principle, changes in pressure only affect the equilibrium position if the total number of moles of gas is different on the two sides of the reaction.

c) Increase in Concentration of N2 - Increasing the concentration of N2 will shift the equilibrium to the right, favoring the formation of more NO. This is because the reaction will try to counteract the increase in N2 concentration by producing more NO.

d) Increase in Concentration of O2 - Similarly, increasing the concentration of O2 will also shift the equilibrium to the right, favoring the formation of more NO. The reaction will respond to the increase in O2 concentration by producing more NO to counteract the change.

In summary, increasing the temperature, concentration of N2, or concentration of O2 will all favor the formation of more NO, while changes in pressure will not have a significant effect on the equilibrium position in this particular reaction.
