600\,\text{K}

the forward rate for the reaction

C \rightleftharpoons D

is measured to be

5.0 \times 10^{-3}\,\text{mol}\,\text{L}^{-1}\,\text{s}^{-1}

, whereas the reverse rate is

2.0 \times 10^{-4}\,\text{mol}\,\text{L}^{-1}\,\text{s}^{-1}

. What is the most likely net change occurring at this temperature? (a) Product

D

is being converted to reactant

C

overall. (b) The forward and reverse rates are essentially equal, so no net change occurs. (c) Reactant

C

is being converted to product

D

overall. (d) Neither

C

nor

D

is reacting because the system is at equilibrium.
