The Order of the reaction `2A+B+C to ` Product , is found to be 1,2 and 0 w.r.t A,B and C respectively .If the concentration of each reactant is increased by two then the find of rate of reaction.

Explanation

To solve the problem step by step, we will first write the rate law expression based on the given orders of the reaction and then calculate the rate of reaction when the concentrations are doubled.

### Step 1: Write the Rate Law Expression
Given the reaction:
\[ 2A + B + C \rightarrow \text{Products} \]

The order of the reaction with respect to each reactant is:
- 1 with respect to A
