Problem

The table lists the forward and reverse reaction rates for the gas-phase reaction X ⇌ Y in a closed vessel. Time (min) | Rate_forward (mol·L⁻¹·min⁻¹) | Rate_reverse (mol·L⁻¹·min⁻¹) 0 | 0.40 | 0.00 1 | 0.25 | 0.10 2 | 0.15 | 0.15 3 | 0.15 | 0.15 Determine the earliest time at which the system can reasonably be considered to have reached dynamic equilibrium.
