For the reaction C(s) + CO₂(g) ⇌ 2CO(g), what happens to the equilibrium if the pressure is increased at a constant temperature?
Shifts to the right (products)
Shifts to the left (reactants)
No change occurs
The value of Kc increases
📝 Detailed explanation
The right side has 2 moles of gas, while the left side has 1 mole of gas (Carbon is solid). Increasing pressure shifts equilibrium toward the side with fewer gas moles (the left).
