Question 1

For the reaction: 2 N2O5(g) → 4 NO2(g) + O2(g) the rate law is:

= k[N2O5]

At 300 K, the half-life is 2.50 × 104 seconds and the activation energy is 103.3 kJ/mol.  At what temperature is the half-life 400. seconds?
◦ 273 K
◦ 333 K
◦ 3.04 K
◦ 304 K
◦ 296 K

Question 2

For the reaction: 2 NO2(g) → 2 NO(g) + O2(g) concentration-time data are:

t(s) [NO2] log[NO2]
0.00 2.000 0.300 0.500
0.40 1.467 0.166 0.682
0.80 1.076 0.032 0.929
1.20 0.789 -0.103 1.267
1.60 0.579 -0.237 1.727
2.00 0.424 -0.373 2.358

What is the order of the reaction with respect to [NO2]?
◦ zero
◦ first
◦ second
◦ third
◦ 2 + 2
