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 B into A.
d) There is a net conversion of A into B.
