Chemistry Question from JEE Main 2025 · 2 April, Shift 1

For the reaction $A \rightarrow$ products, the half-life $t_{1/2}$ varies with the initial concentration $[A]_0$ as shown in the graph below.

The reaction was started with $2.5 \, \text{mol L}^{-1}$ of $A$. The concentration of $A$ at $10$ minutes is _____ $\times 10^{-3} \, \text{mol L}^{-1}$ (nearest integer).
