1. What is the unit of the rate constant for a second-order reaction?

mol/L·s · L²/mol·s · s⁻ · mol/L²·s

2. Which of the following factors does NOT affect the rate of a chemical reaction?

Concentration · Temperature · Surface area · Color of reactants

3. In a zero-order reaction, the rate of reaction is independent of which factor?

Temperature · Concentration of reactants · Surface area · Catalyst presence

4. The rate of a reaction is defined as the change in concentration of a reactant or product per unit time. What is the general form of the rate expression?

Rate = k[A]^n · Rate = k[A][B] · Rate = k[A]^2 · Rate = k[A][B]^2

5. Which of the following statements is true regarding the Arrhenius equation?

It relates rate to temperature. · It is only applicable to first-order reactions. · It includes the activation energy. · It can be used for all reactions.
