Rate Law Application

Question

For 2A + B → Products with rate = k[A]²[B], overall order is:

RankGuru · Accepted Answer

1. **Rate Law**: $Rate = k[A]^x[B]^y$.
2. **Definition of Order**: The overall order of a reaction is the **sum of the exponents** of all concentration terms in the rate law.
3. **Analysis of Given Law**:
   - Order with respect to $A$ is $2$.
   - Order with respect to $B$ is $1$ (implied as no exponent is shown).
4. **Calculation**: Overall Order $= 2 + 1 = 3$.
5. **Note**: The stoichiometric coefficients ($2$ for $A$) do not determine order unless the reaction is elementary.
