Question

If your pond has an initial concentration of the toxicchemical of 1.94 M, and the decomposition rate is 0.43month1, how long will it be until you can stockthe pond with trout?
Note that the units of the rate constant k, will tellyou whether the reaction is zero, first, or second order. Use theintegrated rate law and report your answer to 1/100th of amonth If your pond has an initial concentration of the toxicchemical of 1.94 M, and the decomposition rate is 0.43month1, how long will it be until you can stockthe pond with trout?

Explanation / Answer

We know that :     The decomposition rate of thesubstance is given as -0.43 month-1               T1/2 = 0.693 / K                T1/2   = 0.693 / 0.43month-1                           = 1.611 month         According to thefirst order of the kinetics :            t = 2.303 / K log [ a ] / [ a-x]                = 2.303 /   0.43month-1   log 1.94 M / 0.97M                  = 1.612 / 100 month                  = 0.01612 month.                           = 1.611 month         According to thefirst order of the kinetics :            t = 2.303 / K log [ a ] / [ a-x]                = 2.303 /   0.43month-1   log 1.94 M / 0.97M                  = 1.612 / 100 month                  = 0.01612 month.
