The decomposition of dinitrogen pentoxide in carbon tetrachloride solution at 30°C is first order in N205 During one experiment it was found that when the initial concentration of N,0s was 1.50 M, the concentration of N20 dropped to 0.330 M after 273 min had passed. Based on this experiment, the rate constant for the reaction is min Submit Answer Retry Entire Group 7 more group attempts remaining

Explanation / Answer

we have:

[N2O5]o = 1.50 M

[N2O5] = 0.330 M

t = 273.0 min

use integrated rate law for 1st order reaction

ln[N2O5] = ln[N2O5]o - k*t

ln(0.33) = ln(1.5) - k*273

-1.1087 = 0.4055 - k*273

k*273 = 1.5141

k = 5.55*10^-3 min-1

Answer: 5.55*10^-3 min-1
