A first order reaction has specific reaction rate of `10^(-3) s^(-1)` . How much time will it takes for 10 gm of the reactant to reduce to 2.5 gm ?

Explanation

To solve the problem, we will use the first-order reaction kinetics formula. The formula for a first-order reaction is given by:

\[ t = \frac{2.303}{k} \log \left( \frac{[A]_0}{[A]} \right) \]

Where:
- \( t \) is the time taken for the reaction,
...
