How many times will the rate of the reaction `2A+B to A_(2)B` change is the concentration is expressed in mol/mL ?

Explanation

To solve the question of how many times the rate of the reaction `2A + B → A2B` will change if the concentration is expressed in mol/mL instead of mol/L, we can follow these steps:

### Step 1: Understand the Rate Expression
The rate of a reaction is generally expressed in terms of the concentrations of the reactants raised to their respective powers (which correspond to the stoichiometric coefficients in the balanced equation). For the reaction `2A + B → A2B`, the rate can be expressed as:
\[ R = k [A]^m [B]^n \]
where \( k \) is the rate constant, and \( m \) and \( n \) are the orders of the reaction with respect to A and B, respectively.
