Given: plot of [A] versus time → therefore the reaction is a zeroth-order reaction
The integrated rate law for this reaction is:
The half-life equation for a zeroth-order reaction is:
The decomposition of ethanol (C2H5OH) 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 -4.00 x 10-5 mol/L•s.
b. If the initial concentration of C2H5OH was 1.25 x 10-2 M, calculate the half-life for this reaction.
