1. A reaction A + B â C obeys the following rate law: Rate·k[A],[B]. a. If㧠is doubled, how will the rate change? Will the rate constant change? What are the reaction orders for A and 8? What is the overall reaction order? b. c What are the units of the rate constant? 2. Consider the following reaction: 2NO +2H2 N+2HO (all gases) The rate law for this reaction is first order in H, and second order in No. law. a. b. If the rate constant for this reaction at 1000 Kelvin is 6.0E4M's, what is the reaction rate when [NO].025 M and (H2]-.015 M? What is the reaction rate at 1000 Kelvin when the concentration of NO is increased to 0.10 M, while the concentration of H2 is 0.010 M? c. 3. The reaction between ethyl bromide (CH,Br) and hydroxide ion is: it is first order with respect to each reactant. When ethyl bromide is 0.0477 M and hydroxide ion is 0.100 M, the rate of disappearance of ethyl bromide is 1.7 E -7 M/2. a. What is the value of the rate constant? b. What are the units of the rate constant?
