Given data:
Volume of reactor = 100 dm3
Initial concentration of A = 0.01 mol/ dm3
Conversion of A = 70 %
(a). (i)
The elemental reaction is,
It is also given that the reaction is liquid phase reaction, therefore the system is CVRS(constant volume reaction system).
The value of k = 0.05mol/h·dm3
From the unit of rate constant it is concluded that the reaction is of zero order.
Therefore the rate of reaction becomes,
(ii)
The rate of reaction is,
k = 0.05 h–1
From the unit of rate of reaction, it is concluded that the reaction is of first order.
Therefore the value of rate of reaction becomes,
