A first order reaction has specific rate constant of `10^(-3)s^(-1)`. How much time will it take for 10g to reduce to half the quantity (i.e. 5g) ?

Explanation

To solve the problem of how much time it will take for a first-order reaction to reduce 10g of a substance to 5g, we can use the first-order kinetics equation. Here’s a step-by-step solution:

### Step 1: Identify the given values
- The specific rate constant \( k = 10^{-3} \, s^{-1} \)
- Initial quantity \( A_0 = 10 \, g \)
- Final quantity \( A_t = 5 \, g \)

### Step 2: Use the first-order kinetics equation
