What is the unit of the rate constant (k) for a first-order reaction?

In a reaction A → Products, the half-life (t₁/₂) is independent of the initial concentration. What is the order of the reaction?

The rate law for the reaction 2NO + O₂ → 2NO₂ is found to be rate = k[NO]²[O₂]. What is the overall order of the reaction?

For a second-order reaction, the plot of which of the following versus time is a straight line?

If the rate constant of a reaction doubles when temperature is increased from 300 K to 310 K, what is the approximate activation energy (Ea) of the reaction? (Use Arrhenius equation and R = 8.314 J/mol·K)

Which of the following statements is TRUE for zero-order reactions?

The integrated rate law for a zero-order reaction is:

In the reaction 2A + B → Products, the rate law is rate = k[A][B]. What is the molecularity of the rate-determining step?

Which factor does NOT affect the rate constant (k) of a reaction?

For the reaction A → Products, the plot of ln(rate) vs ln[A] gives a slope of 1.5. What is the order of the reaction with respect to A?
