In the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g), what effect does increasing the pressure have? (2020)
Shifts equilibrium to the left
Shifts equilibrium to the right
No effect on equilibrium
Increases the rate of reaction
Increasing the pressure shifts the equilibrium towards the side with fewer moles of gas. In this case, it shifts to the right, producing more SO3.

Q
Q: In the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g), what effect does increasing the pressure have? (2020)
Solution: Increasing the pressure shifts the equilibrium towards the side with fewer moles of gas. In this case, it shifts to the right, producing more SO3.
Steps: 7
Step 1: Identify the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g).
Step 2: Count the number of gas molecules on each side of the reaction.
Step 3: On the left side (reactants), there are 2 SO2 and 1 O2, totaling 3 gas molecules.
Step 4: On the right side (products), there are 2 SO3, totaling 2 gas molecules.
Step 5: Understand that increasing pressure in a reaction favors the side with fewer gas molecules.
Step 6: Since the right side has fewer gas molecules (2) compared to the left side (3), increasing pressure will shift the equilibrium to the right.
Step 7: This shift to the right means more SO3 will be produced.
