Unformatted text preview: UNIT VII KINETICS & NUCLEAR CHEMISTRY TEST NAME________________________ I. Multiple Choice. Select the best possible answer: (10 pts) Questions 1-3 A + B C The following are possible rate laws for the hypothetical reaction given above: a. rate = k[A] b. rate = k[A] 2 c. rate = k[A][B] d. rate = k[A] 2 [B] e. rate = k[A] 2 [B] 2 ______ 1. This is the rate law for a first order reaction ______ 2. This is the rate law for a reaction that is second order with respect to B. ______ 3. When [A] and [B] are doubled, the initial rate of reaction will increase by a factor of two. ______ 4. A multistep reaction takes place by the following mechanism. A + B C + D A + C D + E Which of the species shown above is an intermediate in the reaction? a. A b. B c. C d. D e. E ______ 5. H 2 (g) + I 2 (g) 2 HI(g) When the reaction above takes place in a sealed isothermal container, the rate law is rate = k[H 2 ][I 2 ] If a mole of H 2 gas is added to the reaction chamber, which of the following will be true? a. The rate of reaction and the rate constant will increase b. The rate of the reaction and the rate constant will not change. c. The rate of the reaction will increase and the rate constant will decrease. d. The rate of reaction will increase and the rate constant will not change. e. The rate of reaction will not change and the rate constant will increase. A + B C ______ 6. When the reaction given above takes place, the rate law is: rate = k[A] If the temperature of the reaction chamber were increased, which of the following would be true?If the temperature of the reaction chamber were increased, which of the following would be true?...
