Name: 15. The reaction d. zero e. fourth s first order in B and A. The overall order ofthe reaction is a. first. b. second c third 16. In a rate law, the partial orders are determined by the reactant concentrations. b. the stoichiometric coefficients c. the product concentrations d. experinment e, the difference between the forward and reverse rates The reaction CHCIO+CHg)Cade)+HC g) has the following rate law: Rate-uclciljal, rthe concentration of CHCly is increased by a factor of five while the concentration of Clh is kept the same, the rate will 17. a. double b triple d. e. increase by a factor of five. decrease by a factor of one-fifth. c. stay the same. The reaction 2N00 + Orlg) 2NOO has the following rate law: Rate-uo,INO). If the concentration of reduced by a factor oftwo, the rate will a. double b. quadruple c. be reduced by one-quarter. 18. d. be reduced by one-half e. remain the same. 19. The energy needed to form an activated complex is called a. collision energy. b. kinetic energy. c. activation energy. d. potential energy. e. thermodynamic energy.

Explanation / Answer

given

first order with respect to A and B so rate law will be

- ra = k [A][B]

so overall order will be 1 + 1 =2

Answer is second order reaction

---------------------------------------------

partial orders can be determined only by experiments.

not by any other means

Answer is (d)
