Activation energy from a decomposition.
. The rate constant for the decomposition of C2H6 is given in the table below. Calculate the activation energy.
105 k/s Temperature/K
2.5 823
4.7 833
8.2 843
12.3 853
23.1 863
35.3 873
57.6 883
92.4 893
141.5 903
This is what i have so far...
Ea = R x (("T1" x "T2") / ("T2" - "T1")) x ln("k2" / "k1")
8.314 x (823 x 903) / (903 – 823) x In(141.5 / 823) = ?
I haven't a clue if this is even right, am i meant to plot a graph?
Any help would be very much appreciated.
