For each case, the direction in which equilibrium shifts is:
(a) Temperature is decreased.
(b) Pressure is increased by adding  at constant T.

Step 1 — Case (a): Temperature decreased
Reaction is endothermic ( kJ). By Le Chatelier's principle:
- Decreasing T removes heat  equilibrium shifts in the direction that produces heat  backward (toward , reactant)

Step 2 — Case (b): Pressure increased by adding  at constant T
-  is an inert gas added at constant temperature
- At constant T, adding inert gas at constant volume  partial pressures of  and  unchanged
-  no change in equilibrium position

Answer: Option (3) — (a) toward reactant, (
