Question
1. The decomposition of ethanol (C₂H,OH) on an alumina (Al2O3) surface
C₂H5OH(g) →→ C₂H4(g) + H₂O(g)
was studied at 600 K. Concentration versus time data were collected for this reaction, and a
plot of [A] versus time resulted in a straight line with a slope of 24.00 x 10³ mol/L s.
a)
Determine the rate law, the integrated rate law, and the value of the rate constant for
this reaction.
b)
If the initial concentration of C₂H5OH was 1.25 x 10-2 M, calculate the half-life for this
reaction.
c)
How much time is required for all the 1.25 x 10-2 M C₂H5OH to decompose?
