Question

Base your answer on the information below and on your knowledge of chemistry.Nitrogen dioxide, NO₂, is a dark brown gas that is used to make nitric acid and to bleach flour. Nitrogen dioxide has a boiling point of 294 K at 101.3 kPa. In a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, N₂O₄. This equilibrium is represented by the equation below.$2NO_2(g) \rightarrow N_2O_4(g) + 58kJ$State one stress, other than adding or removing NO₂(g) or N₂O₄(g), that would increase the amount of the dark brown gas.

Answer 1

Answer:

There are two possible answers to the question

I) decreasing the pressure of the system

II) decreasing the temperature of the system

Explanation:

Looking at the equation of the reaction, it can be seen that the reaction is endothermic. This implies that decreasing the temperature favours the reverse reaction and more NO2 is produced.

Secondly, decreasing the pressure drives the equilibrium position towards the side having the higher total volume hence decreasing the pressure favours the reverse reaction and more NO2 is produced.
