10. Samples of a new anticancer drug in aqueous solution were stored at 45°C, 60°C and 75°C. The first-order rate constants for the decomposition at different temperatures were determined as follows: 45 60 75 Temperature (°C) Rate Constant (day'') 0.052 0.069 0.089 Considering that the drug expires once the concentration decreases to 90% of the original, calculate the expiration time of the anticancer drug at 25°C (room temperature).

The decomposition of nitramide in aqueous solution at 25 °C NH2NO2(aq)------->N2O(g) + H2O(l) is first order in NH2NO2. During one experiment it was found that when the initial concentration of NH2NO2 was 0.458 M, the concentration of NH2NO2 dropped to 0.117 M after 21860 s had passed. Based on this experiment, the rate constant for the reaction is _________s-1.
The decomposition of nitramide in aqueous solution at 25 °C NH2NO2(aq)N2O(g) + H2O(l) is first order in NH2NO2 with a rate constant of 4.70×10-5 s-1. If the initial concentration of NH2NO2 is 0.122 M, the concentration of NH2NO2 will be 3.55×10-2 M after________ s have passed.
In a study of the decomposition of nitramide in aqueous solution at 25 degree C NH_2NO_2(aq) rightarrow N_2O(g) + H_2O(1) the concentration of NH_2NO_2 was followed as a function of time. It was found that a graph of ln[NH_2NO_2] versus time in seconds gave a straight line with a slope of -6.72 times 10^-5 s^-1 and a y-intercept of -0.863. Based on this plot, the reaction is order in NH_2NO_2 and the rate constant for the reaction is s^-1.
