$
with initial concentration $x mol L ^{-1}$, has a half life period of 2.5 hours. For the same reaction with initial concentration $\left(\frac{ x }{2}\right) mol L ^{-1}$ the half life is
$
A \longrightarrow \text { Product }
$
with initial concentration $x mol L ^{-1}$, has a half life period of 2.5 hours. For the same reaction with initial concentration $\left(\frac{ x }{2}\right) mol L ^{-1}$ the half life is
- A$(2.5 \times 2)$ hours
- B$\left(\frac{2.5}{2}\right)$ hours
- ✓2.5 hours
- DWithout knowing the rate constant, $t_{1 / 2}$ cannot be determined from the given data
