The table bellow gives the concentrations of C2H4O (g) as a function of time at 690K for the following reaction equation: C2H4O (g) -------> CH4 (g) + CO (g)
[C2H4O]/ M t/min
0.0860 00.0465 500.0355 720.0274 930.0174 130
Verify that this is a first order reaction by plotting 1n ([C2H40]/M versus time and determine the value of the rate constant.
