Solve question 4. 1. The rate constant of a reaction has units of 1/M-s. What is the order of its rate law?(A) O(B) 1(C) 2(D) Some other order2. A first order reaction has a half-life of 5.0 seconds. If the concentration of the reactant wasoriginally 8.00 M, how long will it take to reach a concentration of 1.00 M?(A) 3.0 seconds (B) 15. seconds (C) 8.0 seconds (D) None of these(A) It is doubled(C) It is four times as fast3. The rate expression for a reaction is: rate = k [A] [B]. The temperature is held constant.The initial concentrations are changed. [A] is halved.How does the new initial rate compare to the old initial rate?(B) It is one quarter as fast(D) It is halved(E) It is not changed4. For the chemical equation, A + 2B 3 C, the rate of disappearance of B was measuredand found to be 0.500 M/s. What is the rate of appearance of C?(A) 0.500 M/s (B) 0.250 M/s (C) 0.750 M/s (D) 0.333 M/s5. Step 1, NO (g) + O. (g) → NO₂ (g) + O₂(g)Step 2, O (g) + NO₂ (g) → NO (g) + O₂ (g)If the reaction, O(g) + O. (g) → 2 O₂ (g) occurs using the above 2 step process, which of thefollowing is true?

As per the student's request I'm solving question number 4.
