Question

Ulfur dioxide gas can react in the presence of oxygen and vanadium(V) oxide to form sulfur trioxide. Sulfur trioxide is the only product of the reaction. Which statement correctly describes this reaction?
1) Sulfur dioxide is a catalyst
2) Sulfur trioxide is a catalyst
3) Oxygen is a catalyst
4) Vanadium (V) oxide is a catalyst

Answer 1

According to the illustration, the vanadium (V) oxide would be a catalyst.

What are catalysts?

Catalysts are substances that are utilized in reactions that are not themselves consumed in reactions but only speed up the rate of the reactions.

Catalysts speed up the rate of reactions by lowering the activation energy of the reactants.

Sulfur dioxide reacts with oxygen to produce sulfur trioxide. The vanadium (v) oxide is not consumed in the reaction. Thus it only serves as a catalyst.
