Give that the rate of a certain reaction is given below, which of the following statements is true?

• Give that the rate of a certain reaction is given below, which of the following statements is true? Rate = k[BrO3-][Br-][H+] 1. the reaction is 3rd order 2.the reaction is 2nd order 3. the reaction is 1st order 4. the reaction is 3st order with respect to [H+] 5. The reaction is 1st order with respect to [H+] 6. k is the rate constant 7. the reaction is 0 order. Could you please also explain how you figured this question out??

• Answer:

  The order of a reaction is the sum of the exponents to which concentration terms in the rate law are raised. Thus if a reaction has a rate law rate = k[A]^a[B]^b[C]^c the reaction has order a in substance A, b in B, c in C and overall order (a+b+c). Your reaction is 1st order in each of the three reactants in the rate law and third order overall
