alleryA catalyst on the bench changes:
AThe equilibrium constant, shifting K by a known factor
BThe position of equilibrium toward products only at start
CThe activation energy and rate, without shifting equilibrium
DThe standard Gibbs energy of the reaction permanently shifts
Answer & Solution
Correct answer: C. The activation energy and rate, without shifting equilibrium
A catalyst lowers $E_a$ and speeds both forward and reverse rates equally
equilibrium is unchanged.
