What does the steady-state approximation assume about a reactive intermediate?
A.Its concentration stays roughly constant
B.Its concentration is zero
C.It equals the reactant concentration
D.It grows indefinitely
Explanation
Core Concept
After a brief buildup, the intermediate is consumed about as fast as it forms, so d[intermediate]/dt ≈ 0. Setting the rate of change to zero lets you solve for its concentration.
Correct Answer
AIts concentration stays roughly constant
