Cyclobutane decomposes to ethylene according to the equation:
C4Hg(g) → 2C2H4(g)
Determine the value of rate constant for the reaction based on the following pressures, which were recorded when the reaction was carried out at 430 degree C in a constant-Volume Vessel.
Time (s) mmHg
0 400
2000 316
4000 248
6000 196
8000 155
10000 122

Conc = initial conc * e^(-kt)
Rearrange and substitute:
ln(316/400) = -k (2000s)
k=.000118 s^-1
