The rate of decomposition of N2O3 (g) to NO2 (g) and NO (g) is followed by measuring NO2 at different times. The following data are obtained. [NO2 (mol/L) 0 0.193 0.316 0.427 0.784]
t (s) 0 884 1610 2460 50,000]
The reaction follows a first-order rate law.
Calculate the specific rate constant. Assume that after 50,000 s all the N2O3( g) had decomposed.
