Question

For the reaction: NO₂(g) + CO(g) = NO(g) + CO₂(g),

the time-dependent changes for [NO₂] and [CO] data were individually graphed against time to yield the following plots:

(a) Deduce the rate law for the above reaction. (b) When the reaction was carried out at 225^oC, it took 3.00 x 10³ seconds for the concentration of NO₂ to decrease from 0.500 M to 0.380 M. What is the value of the rate constant k at 225^oC (with appropriate unit)? (Answer: (b) k = 2.11 x 10-4 M^–1 ∙ s^–1)
