Problem
For the reaction 2X(g)⇌3Y(g) in a sealed container, the forward and reverse reaction rates are each 4.0×10−5molL−1s−1 at a particular instant.
(i) What is the net rate of change of [X] at that instant?
(ii) What is the net rate of change of [Y] at that instant?
(iii) Briefly justify why both concentrations remain constant despite the unequal stoichiometric coefficients.
