Question:

In a reaction, if the concentration of reactant A is tripled, the rate of reaction becomes twenty-seven times. What is the order of the reaction?

Solution:

Consider a rate of a reaction with reactant A

Rate = k[A]α

27 ˟ Rate = k[A]α

By dividing the equations we get α = 3

Therefore the order of the reaction becomes three.
