Specific reaction rate of a gaseous reaction is `6.8 xx 10^(-8)"atmoshere"^(-1)"second"^(-1)`. Calculate its specific reaction rate in litre `"mole^(-1)"second"^(-1)` unit.

Explanation

To convert the specific reaction rate from units of atm^(-1) s^(-1) to L mol^(-1) s^(-1), we can follow these steps:

### Step-by-Step Solution

1. **Identify the given specific reaction rate**:
The specific reaction rate is given as:
\[
k = 6.8 \times 10^{-8} \, \text{atm}^{-1} \, \text{s}^{-1}
