Question

Wich plot shows a first-order reaction with respect ot reactant A? 3. The reaction 2NO rightarrow O_2, has rate constant of 3.6 times 10^2 m^-1 s^-1. When [NO] -2.8times10^-3 M, what is the rate of change in M-s^-1 for N_2? (A) 5.6 times 10^-2 (B) 1.8 times 10^-4 (C) 2.8 times 10^-7 (D) 5.0 times 10^5 5. The decomposition of N_2O_4 is studied at 20 degreeC and at 80 degreeC. Which statement explains why the rate at 80 degreeC is greater than at 20 degreeC? (A) he activation energy is lower at 80 degreeC. (B) The activation energy is higher at 80 degreeC. (C) The concentration of a gas increases with increasing temperature. 6. Compound A decomposes to form compound B. when 1/[A] is plotted versus time, a straight line with a slope of 0.53 M^-8 min^-1 results. What is the rate law? (A) rate = 0.53 M^-1 min^-1 (B) rate = 0.53 M^-1 min^-1 [A] (C) rate = 0.53 M^-1 min^-1 [A]^2 (D) More information is necessary.
