Solution

Solution Steps

Step 1: Analyze the Graph at 20 µs

At 20 µs, observe the concentrations of reactant [A] and product [B] from the graph. The concentration of [A] is decreasing, and the concentration of [B] is increasing.

Step 2: Determine Reaction Equilibrium Status

Since the concentrations of [A] and [B] are still changing at 20 µs, the reaction is not at equilibrium.

Step 3: Compare Forward and Reverse Reaction Rates

Given that [A] is decreasing and [B] is increasing, the forward reaction (A → 2B) is faster than the reverse reaction at 20 µs.
