Which of the following statements is correct regarding the properties of ammonia?

If a reaction vessel containing an equilibrium mixture of N2(g), H2(g), and NH3(g) is compressed at constant temperature, what will happen to the equilibrium?

Consider the reaction of ammonia with metal oxide: $3CuO(s) + 2NH_3(g) \rightarrow 3Cu(s) + N_2(g) + 3H_2O(g)$. If 15.9 g of $CuO$ reacts completely with excess ammonia, what volume of $N_2$ gas is produced at standard temperature and pressure (STP)? (Molar mass of $CuO$ = 79.5 g/mol, Molar volume of gas at STP = 22.4 L/mol)

Given the following reactions, identify the statement that accurately describes ammonia's role:

Predict the major consequence of a malfunction in the Haber-Bosch process at a large-scale fertilizer plant that leads to a significant reduction in ammonia production.

A researcher is investigating the efficiency of different catalysts for the Haber process. They find that a particular catalyst significantly increases the rate of ammonia formation but also promotes the decomposition of ammonia back into nitrogen and hydrogen. What is the most likely explanation for this observation?

An industrial chemist aims to maximize the yield of ammonia in the Haber process. Which of the following strategies would be the MOST effective, considering both thermodynamic and kinetic factors?

During an experiment, a student attempts to prepare ammonia gas but mistakenly uses concentrated sulfuric acid as the drying agent. Upon testing the gas produced, they find it does not turn red litmus paper blue and lacks the characteristic pungent odor. What is the MOST likely reason for this outcome?

Imagine a scenario where a novel catalyst is developed that allows the Haber process to occur efficiently at room temperature and atmospheric pressure. What far-reaching consequence could this have on global energy consumption and fertilizer production?

Consider a closed system at equilibrium: $N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)$. A small amount of an inert gas (that does not participate in the reaction) is added to the system while holding the volume and temperature constant. What will be the effect on the equilibrium position?

You have 5.0 L of ammonia gas at 25°C and 1.0 atm pressure. You dissolve all of the ammonia in 1.0 L of water. Assuming no volume change upon dissolution and complete conversion to $NH_4OH$, calculate the approximate hydroxide ion concentration ($[OH^-]$) in the resulting solution. (Assume $K_b$ for $NH_3$ is $1.8 \times 10^{-5}$)
