Questions: 3 Which type of chemical reaction occurs at a rate proportional to the concentration of the square of a single reactant? Zero-order reaction First-order reaction Second-order reaction Mixed-order reaction

Solution Steps

• A chemical reaction where the rate is proportional to the concentration of the square of a single reactant is described by the rate law: \( \text{Rate} = k[A]^2 \).

• The rate law \( \text{Rate} = k[A]^2 \) indicates that the reaction rate depends on the concentration of the reactant raised to the power of 2.

• A reaction with a rate law of \( \text{Rate} = k[A]^2 \) is classified as a second-order reaction.
