Question
Ehylene oxide, C2H4O, decomposes when heated to give methane and carbon monoxide.
C2H4O(g) → CH4(g) + CO(g)
The following kinetic data were observed for the reaction at 688K:
Expriment |
Initial Concentration of Ethylene Oxide |
Initial Rate |
Exp. 1 | 2.72x10-3M | 5.57x10-7 M/s |
Exp 2 | 5.44x10-3M | 1.11x10-6 M/s |
What is the value of the rate constant for the reaction? Express your answer to three significant figures.
Just enter the number (e.g. 2.48x10^-4) and the unit.
Note: Your answer is assumed to be reduced to the highest power possible.
