Chemistry Question from JEE Main 2025 · 28 January, Shift 1

For a given reaction $R \rightarrow P$, $t_{1/2}$ is related to $[A]_0$ as given in the table:

Given: $\log 2 = 0.30$. Which of the following is true?

A. The order of the reaction is $\frac{1}{2}$. B. If $[A]_0$ is $1 \, \text{M}$, then $t_{1/2}$ is $200\sqrt{10}$ min. C. The order of the reaction changes to $1$ if the concentration of reactant changes from $0.100 \, \text{M}$ to $0.500 \, \text{M}$. D. $t_{1/2}$ is $800$ min for $[A]_0 = 1.6 \, \text{M}$.
