Representations of Equilibrium Practice Test

A closed system contains the reversible gas-phase reaction $2\text{NO}(g)+\text{Cl}_2(g) \rightleftharpoons 2\text{NOCl}(g)$. A student measures concentrations early in the run, before any concentrations become constant. Based only on the table, what is the direction of the net reaction progress during the interval shown?

A sealed vessel contains the reversible reaction $\text{PCl}_5(g) \rightleftharpoons \text{PCl}_3(g)+\text{Cl}_2(g)$. A student records concentrations shortly after the reaction begins (before any concentration becomes constant). Using only the table, what is the direction of the net reaction progress over the interval shown?
