Ethanal vapour undergoes thermal decomposition in the reaction C₂H4O(g) CH4(g) + CO(g) Analysis Questions a) Use the data in Table 1, plot a labelled graph of the concentration of ethanol versus time. The following data was recorded: Table 1: Concentration of Ethanal During Thermal Decomposition [C₂H₂O] (mol/L) 0.360 0.290 0.250 0.200 0.180 0.150 0.130 0.110 0.090 0.080 Time (s) 0 100 185 270 420 575 730 950 1250 1440 b) From the graph, determine the average rate of reaction between the times t= 0s and t = 420 s. c) From the graph, determine the instantaneous rate of decomposition of ethanal when its concentration is 0.200 mol/L at 270 s. Draw the tangent line on the curve d) From the graph, determine the initial rate of reaction. Draw the tangent line on the curve.
