Rate of reaction depends on the concentration of reactant.
So, if the concentration of reactant is more, rate will be more.
As reaction passes, reactants are being converted to products.
So, concentration of reactant is decreasing with time.
This leads to decrease in rate.
Add Answer to:
A reaction is started by mixing reactants. As time passes, the rate decreases. Explain this behavior...

Explain the role of the entropy of mixing of reactants and products in determining the composition of a reaction mixture at equilibrium. In what situation will the physical process of mixing have the largest effect? Explain why. *As you read over your answer make sure that you have made it clear you understand the definition of equilibrium from the perspective of reaction spontaneity. Be sure to give enough information to show your understanding of the context and meaning of other...

HI HCI reactants Reaction intermediates are species that are formed in one step of a mechanism and consumed in another step. For example, can act as an intermediate in the following reaction: H2(g) + 2Cl(g) + 2HCl(g) + 12(g). You can often express the concentration of in terms of the concentrations of the of the overall reaction to be consistent with the experimentally observed rate law as the overall reaction...

Most of the time, the rate of a reaction depends on the
concentration of the reactant. In the case of second-order
reactions, the rate is proportional to the square of the
concentration of the reactant.
Select the image to explore the simulation, which will help you
to understand how second-order reactions are identified by the
nature of their plots. You can also observe the rate law for
different reactions.
In the simulation, you can select one of the three different...
