Problem 10E

The conversion of ammonium cyanide to urea is a second-order reaction. This means that the concentration C of ammonium cyanide at time t is given by 1/C = kt + l/C0, where C0 is the initial concentration and k is the rate constant. Assume the initial concentration is known to be 0.1 mol/L exactly. Assume that time can be measured with negligible uncertainty.a. After 45 minutes, the concentration of ammonium cyanide is measured to be 0.0811 ± 0.0005 mol/L. Estimate the rate constant k , and find the uncertainty in the estimate.________________b. Use the result in part (a) to estimate the time when the concentration of ammonium cyanide will be 0.0750 mol/L, and find the uncertainty in this estimate.

Step-by-Step Solution:

Step 1 of 3:

The experiment under consideration here is conversion of ammonium cyanide to urea.

The concentration C of ammonium cyanide at time t is given by, =kt+ where is the initial concentration of ammonium cyanide, k is rate constant.

It is also given that =0.1mol/L.
