Determine the overall order of the reaction:

rate = k[A][B]⁰[D]

• First order

• Zero order

• Second order

• Third order

The possible unit for rate constant (k) base on the rate law is:

rate = k [D][E]⁰

• Ms^-1

• Min

• Min^-1

• M^-1s^-1

The rate constant for the reaction is 0.18 hour^-1 at 20^oC. What is the concentration of H₂O₂ after 3 hours if the initial concentration is 0.80 M?

• 0.466 M

• 0.799 M

• 0.50 M

• 0.22 M
