Problem

For the reversible reaction A ⇌ B at a certain moment the forward rate is 0.015 mol·L⁻¹·s⁻¹ and the reverse rate is 0.022 mol·L⁻¹·s⁻¹. Which statement describes the net change at this instant? (a) The system is at equilibrium; no net change occurs. (b) The direction of net change cannot be determined from the rates alone. (c) There is a net conversion of BB into AA. (d) There is a net conversion of AA into BB.
