AP Chem 5.2 Rate Laws Quiz

Use the data given in the table to determine the rate law for the reaction: 2NO + Br₂ → 2NOBr

• rate = k[NO][Br₂]

• rate = k[NO][Br₂]²

• rate = k[NO]²[Br₂]

• rate = k [NO]²[Br₂]²

• rate = k [NO]²

• tweezers

• forceps

• beaker tongs

• spatula

A possible rate law for a third overall order of a reaction is __________________

• Rate = k [A]²[B]²
• Rate = k [A][B]³
• Rate = k [A]³ [B]
• Rate = k [A]²[B]

Answer explanation

The overall order of a rate law is the sum of the individual rate orders.

Write the rate law for the reaction aA → bB if the reaction is third order in A. [B] is not part of the rate law.

• Rate =k[A]
• Rate =3[A]
• Rate =k[3A]
• Rate =k[A]³
