The gas phase decomposition of nitrogen dioxide at 383 °C NO2(g)NO(g) + ½ O2(g) is second order in NO2. In one experiment, when the initial concentration of NO, was 0.169 M, the concentration of NO, dropped to 4.55×10² M after 20.6seconds had passed. Based on these data, the rate constant for the reaction is M's'.

Question
The gas phase decomposition of nitrogen dioxide at 383 °C
NO,(g)-
→NO(g) + ½ O2(g)
is second order in NO2.
In one experiment, when the initial concentration of NO, was 0.169 M, the concentration of NO, dropped to 4.55x10-² M after 20.6seconds had passed.
Based on these data, the rate constant for the reaction is
M's1.
