Sulfuryl chloride, SO₂Cl₂(g), decomposes at high temperature to form SO₂(g) and Cl₂(g). The rate constant at a certain temperature is 4.68 × 10⁻⁵s⁻¹. What is the order of the reaction?

Question

Quizplus · Accepted Answer

The reaction is a decomposition reaction, where the reactant decomposes into two products. As the reaction rate depends on the concentration of the reactant, the rate of decomposition will decrease with decreasing concentration of the reactant.

The rate law for the reaction can be expressed as:

Rate = k [Sulfuryl chloride]

As the rate of the reaction is directly proportional to the concentration of sulfuryl chloride, the reaction is a first-order reaction. Therefore, the answer is (B) First.

Sulfuryl Chloride, SO2Cl2(g), Decomposes at High Temperature to Form SO2(g)

Sulfuryl Chloride, SO₂Cl₂(g), Decomposes at High Temperature to Form SO₂(g)
