When does pressure not affect a gaseous equilibrium?
AA catalyst is present
BThe temperature is low
CThe reaction is exothermic
DGas moles match both sides
Answer & Solution
Correct answer: D. Gas moles match both sides
With equal gas moles on both sides, changing pressure alters both sides equally, so there is no shift.
