Question

someone help me please!!!

Answer 1

notice the starting concentrations are doubling, but the rate is not doubling, it's increasing faster.

if you divide the rates \(\dfrac{rate_2}{rate_1}\) and \(\dfrac{rate_3}{rate_2}\)=8

you notice that it's increasing to the power of 8, which is cubic.

so the rate law is: \( rate=k[A]^3\)

Answer 2

i meant "increasing by 8" not "to the power of 8"
