What is the order of a reaction if the rate constant has units of L^2 mol^-2 s^-1?

The rate of a reaction triples when the temperature increases from 20°C to 60°C. What is the activation energy for this reaction? (Assume R = 8.314 J/mol·K)

A reaction A + B → C follows the rate law: rate = k[A]^2[B]. If the initial concentration of A is doubled and the initial concentration of B is halved, by what factor will the initial rate change?

What does the Arrhenius equation describe?

For a unimolecular reaction, A → Products, the rate constant at 500 K is 0.01 s⁻¹ and at 600 K is 0.1 s⁻¹. What is the activation energy of the reaction?

The half-life of a first-order reaction is 69.3 minutes. What percentage of the reactant will remain after 231 minutes?

In enzyme kinetics, what does Km represent?

What is the effect of a catalyst on the activation energy of a reaction?

The rate law for a reaction is rate = k[A][B]^2. If the concentration of A is kept constant and the concentration of B is tripled, how will the rate of reaction change?

Which of the following is a factor that affects the rate of a chemical reaction?
