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: 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.
