Consider the following reaction equation and experimental data for the questions below. C2H4+ 3 O2→2 CO2+ 2 H2O
[C2H4] - 0.018M, 0.027M, 0.027M
[O2] - 0.036M, 0.036M, 0.072M
Rate (mol L–1s–1) - 0.0260, 0.0585, 0.0585
a)Determine the experimental rate law (rate expression) for this reaction and write it out. b)How is the rate of disappearance of O2related to the rate of production of CO2?
c)At 170 °C the rate constant is 80.2 mol–1L s–1. If you start with 0.73 mol of C2H4in a 2.0 L vessel, what will the concentration of C2H4be after 3.0 min?
