Per NCERT §6.8.5, what is the effect of adding a CATALYST on the position of equilibrium and on K?
AShifts forward only
BDoubles K
CShifts reverse only
DNo effect on either
Answer & Solution
Correct answer: D. No effect on either
NCERT §6.8.5: catalyst lowers activation energy equally for forward and reverse; speeds attainment of equilibrium but does not alter its position or K.
