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

Explanation

To determine the order of the reaction based on the given information, we can follow these steps:

### Step 1: Write the Rate Law Equation
The rate of a reaction can be expressed using the rate law equation:
\[ r = k[A]^n \]
where:
- \( r \) is the rate of reaction,
- \( k \) is the rate constant,
