Lower rate after another 3 seconds of the given rate is concentration of reactants increased while the concentration of product decreased.

What is the rate of reaction?

Rate of the reaction gives idea about the speed of the completion of the reaction or the formation of product.

Given rate of reaction = 1.8×10⁻⁶ m/sec

After 3 seconds rate of the reaction decreases, which means speed of the formation of product decreases as a result of which:

Concentration of product decreases.
Concentration of reactant increases.

Hence, concentration of reactants increased while the concentration of product decreased.
