When two reactants, $\mathrm{A}$ and $\mathrm{B}$ are mixed to give products $\mathrm{C}$ and $\mathrm{D}$, the reaction quotient, Q at the final stages of the reaction
is zero
decreases with time
is independent of time
increases with time
Solution
In the final stage of the reaction, the reaction is at equilibrium and thus the value of $\mathrm{Q}$ remains constant with time.
