Consider the reaction aA Products.
[A]o = 5.0 M and k= 1.0 x 102 (assume the units are appropriate for each case). Calculate
[A] after 30.0 seconds have passed, assuming the reaction is:
%3D
a) Zero order
b) First order
c) Second order
Dinitrogen pentoxide, N,O5, is not very stable. In the gas
phase or dissolved in a nonaquoes solvent, like carbon
tetrachloride, it decomposes by a first order reaction into
N2O, and O2.
2N2O5
2N204 + O2
The rate law is rate = k[N,Os]. At 45°C, the rate constant
for the reaction in the carbon tetrachloride is 6.22x10-4s

0.1M, how many minutes will it take for the concentration
to drop to 0.01M
