Problem

At 450  K450\;\text{K} the reaction 2 SO2(g)+O2(g)⇌2 SO3(g)2\,\text{SO}_2(g)+\text{O}_2(g)\rightleftharpoons2\,\text{SO}_3(g) is at equilibrium with [SO2_2] =0.20  M=0.20\;\text{M}, [O2_2] =0.10  M=0.10\;\text{M}, and [SO3_3] =0.40  M=0.40\;\text{M}. A single disturbance is applied, and immediately afterward only the product concentration is observed to change, jumping to [SO3_3] =0.60  M=0.60\;\text{M} while the reactant concentrations are unchanged at that instant. Identify the most likely change that was made to the system.
