The reaction 2NO2 → 2NO + O2 obeys the rate law: rate = 1.4 x 10-2[NO2]2 at 500 K . What would be the rate constant at 310 K if the activation energy is 80. kJ/mol? This is a second order reaction, giving k the units of M-1S-1 This will not change with the change in temperature. Do not include units in your answer. Exponential numbers need to be entered like this: 2 E-1 means 2 x 10-1. The rate...
4) A particular irreversible chemical reaction follows the rate law rate =k [A] At a particular temperature the value for the rate constant is k = 3.66 x 10-s. a) In an experiment carried out at that temperature the initial concentration of A in a system is [A]o = 7.66 x 10-2 M. What will the concentration of A be in the system at t = 400. s? [8 points]
