The first-order degradation of a drug was monitored under three different conditions (I, ii, and iii), which resulted in half-lives (in no particular order) of 4 hours, 8 hours, and 10 hours: а. i. at 37 °C. ii. at 37 °C, in the presence of a catalyst. iii. at 21 °C. Identify which half life goes with which set of conditions. For condition i., draw and label a graph of Concentration (mmol/L) vs Time (hr). Start with an initial concentration of 10 mmol/L and show the decay over 40 hours. You may use the grid below or draw your graph by hand. 10 9.5 8.5 7.5 2 6.5 E 5.5 4.5 4 3.5 2.5 1.5 0.5 4 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 Time (hours) -1 Another reaction is found to have an activation energy of 80.3 kJmol.
