In a closed vessel at constant temperature, the reversible reaction occurs: 2SO2(g)+O2(g)⇌2SO3(g)\mathrm{2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g)} At a moment before equilibrium is reached, the following concentrations are measured:
SpeciesCurrent concentration (M)
SO2\mathrm{SO_2}0.05
O2\mathrm{O_2}0.10
SO3\mathrm{SO_3}0.90
In which direction will the net reaction proceed to reach equilibrium?
