Question description

A pharmacist must calculate the shelf life for an antibiotic. The antibiotic is stored as a solid and a fresh solution must be prepared for the patient. The antibiotic is unstable in solution and decomposes according to the following data:

Time (days) [Antibiotic] (mol/L)
01.24 x 10-2
10.0.92 x 10-2
20.0.68 x 10-2
30.0.50 x 10-2
40.0.37 x 10-2

This is a first order process.

Question 1

Calculate the half-life for the antibiotic. The units should be in days and should be calculated to three significant figures

Calculate the rate constant (with appropriate units) for a first order reaction which is 30.0% complete in 363 s.How long will it take for the reaction to go to 95.5% completion?
