2SO2(g) + O2(g) --> 2SO3(g)

What is the correct rate law for this reaction?
  1. r = k[SO2][O2]
  2. r = k[SO3]
  3. r = k[SO2]2[O2]
  4. r = k[SO3]2
  5. r = k[SO3][SO2][O2]
Explanation
Answer: r = k[SO2]2[O2]

When writing a rate law for a chemical reaction, use the concentrations of the reactants raised to the powers of their coefficients. The rate constant, k, is determined experimentally and cannot be determined with the information in this problem. Thus, the correct rate law is r = k[SO2]2[O2].
