Solution :`A+2BrarrC`
REACTION rate is doubled when the concentration of A is doubled. Again when both A and B are made FOUR times, reaction rate also becomes four times. It MEANS reaction rate is independent of the concentration of B. With respect to A, the order is definitely ONE.
`therefore` w.r.t.A,order=1
w.r.t.B,order=0
Overall order = 1
