Chemistry Question from JEE Main 2023 · 30 January, Shift 1

If compound A reacts with B following first-order kinetics with rate constant $2.011 \times 10^{-3} \, s^{-1}$, the time taken by A (in seconds) to reduce from $7 \, \text{g}$ to $2 \, \text{g}$ will be _____. (Nearest Integer)

Given: $\log 5 = 0.698, \quad \log 7 = 0.845, \quad \log 2 = 0.301.$
