Solution

The correct options are
B r1>r2>r3
C r1=r2=r3
D r1<r2<r3
For nth order reaction, the rate of the reaction is given by the expression rate =k[A]n.
The rate of the reaction depends on the rate constant, the reactant concentration and the reaction order.
Although the rate constants are same, nothing is mentioned regarding the reactant concentrations.
The rate of the reaction for three reactions may be same or different.
Hence, any one of the following may be true.
r1=r2=r3
r1>r2>r3
r1<r2<r3
