Expert Solution
Step 1

(a)

(i) time interval = [1.0, 2.0]

Average change of C = concentraion at (2.0) - concentration at (1.0)2.0-1.0 = 0.16-0.331.30

∴ Average change of C = - 0.17

 

(ii) time interval = [1.5, 2.0]

Average change of C = concentraion at (2.0) - concentration at (1.5)2.0-1.5 = 0.16-0.220.5

∴ Average change of C = - 0.12

 

(iii) time interval = [2.0, 2.5]

Average change of C = concentraion at (2.5) - concentration at (2.0)2.5-2.0 = 0.1-0.160.5

∴ Average change of C = - 0.12

 

(iv) time interval = [2.0, 3.0]

Average change of C = concentraion at (3.0) - concentration at (2.0)2.0-1.0 = 0.06-0.161.00

∴ Average change of C = - 0.10
