From the following data, show that the decomposition of hydrogen peroxide is a reaction of the order :
`{:("t (min)",0,10,20),("V (ml)",46.1,29.8,19.3):}`
Where t is the time in minutes and V is the volume of standard `KMnO_(4)` solution required for titrating the same volume of the reaction mixture.

`k=(2.303)/(t)"log"([A_(0)])/([A])`
`k=((2.303)/(t))log((V_(0))/(V_(t)))`
In the present case, V0 = 46.1 ml.
The value of k at each instant can be calculated as follows :

Thus, the value of k comes out to be nearly constant. Hence it is a reaction of the first order.

Consider a tank which initially holds V_(0) liter of brine that contains a lb of salt. Another brine solution, containing b lb of salt per liter is poured into the tank at the rate of eL//"min" . The problem is to find the amount of salt in the tank at any time t. Let Q denote the amount of salt in the tank at any time. The time rate of change of Q, (dQ)/(dt) , equals the rate at which salt enters the tank at the rate at which salt leaves the tank. Salt enters the tank at the rate of be lb/min. To determine the rate at which salt leaves the tank, we first calculate the volume of brine in the tank at any time t, which is the initial volume V_(0) plus the volume of brine added et minus the volume of brine removed ft. Thus, the volume of brine at any time is V_(0)+et-ft The concentration of salt in the tank at any time is Q//(V_(0)+et-ft) , from which it follows that salt leaves the tank at the rate of f(Q/(V_(0)+et-ft)) lb/min. Thus, (dQ)/(dt)=be-f(Q/(V_(0)+et-ft))Q=be A tank initially holds 100 L of a brine solution containing 20 lb of salt. At t=0, fresh water is poured into the tank at the rate of 5 L/min, while the well-stirred mixture leaves the tank at the same rate. Then the amount of salt in the tank after 20 min.
