Given the options: 1. Pressure has no effect: This is incorrect because pressure does affect the equilibrium of reactions involving gases. 2. $P_1 P_2 > P_3$ : This implies that the yield decreases with increasing pressure, which is contrary to what we expect. 4. $P_1=P_2=P_3 \neq 0$ : This would imply that pressure has no effect on the yield, which contradicts Le Chatelier's Principle. Conclusion: The correct option is: (2) $P_1 < P_2 < P_3$ This means that as pressure increases, the yield of $\mathrm{SO}_3$ increases.
