The time taken for the reaction to reach equilibrium in this concentration versus time graph is 4.5 seconds and is denoted as option D.

This refers to the duration in which a certain action or activity takes place with its unit being seconds.

From the graph we can deduce that:

The two blue lines, the concentrations of H₂ and O₂, become flat between 4 and 5 seconds.

The red line, the concentration of H₂O, becomes flat, also, between 4 and 5 seconds.

This therefore means that the time taken for the reaction to reach equilibrium in this concentration versus time graph is 4.5 seconds.
