The rate of reaction typically decreases as the reaction proceeds due to the depletion of reactants, leading to fewer collisions and a lower reaction rate.

Silver nitrate (AgNO3) reacts with organic substances to form black spots of silver. This is a known test for the presence of organic materials. The reaction occurs when AgNO3 comes into contact with skin, cellulose, or other organic compounds, resulting in the formation of dark-colored silver particles.

The rate of reaction when the concentration of reactants is unity is defined as the specific rate constant, a fundamental concept in chemical kinetics that characterizes the reaction rate under standard conditions.
The order of reaction is determined by the sum of the exponents of the concentration terms in the rate equation. Here, the exponents of [A] and [B] are both 1, so the order of reaction is 1 + 1 = 2, making it a second-order reaction.
