1. What conditions of temperature and pressure favor products in the following reaction:
PCl5(g) ⇌ PCl3(g) + Cl2(g) ΔH = 238 kJ/mol
2. Consider the system below. When equilibrium is restored, how will the number of each type of molecule and the concentration of each substance compare to those before the stress was introduced? Complete the following table using the words “decrease,” “same,” or “increase.”
2 NH3(g) ⇌ N2(g) + 3 H2(g) ΔH = 92.4 kJ/mol

3. Nitric acid is produced commercially by the Ostwald process. The first step of the Ostwald process is:
4 NH3(g) + 5 O2(g) ⇌ 4 NO(g) + 6 H2O(g) + energy
In which direction will the above system shift in the following situations:
3. (a) Some NO is added.
