The rate of reaction or speed of reaction for a reactant or product is defined as how fast or slow a reaction takes place. The rate of reaction decreases as the reaction proceeds because the concentration of reactants is high at the start and with time, this concentration decreases and the reaction gets slower. But it can increase also. |
