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.
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...

Given the equilibrium reaction for a general reaction, A+B <->C, explain what happens to the reactants and products from time until the time at which the A reaction reaches equilibrium. (Choose any that are correct) Concentration (mol.dm-3) B С Time (s) Once products are formed in a reversible reaction, reactans can not be formed At equilibrium both the reactant and product concentration are the same At time 0, there are no products. At equilibrium all concentrations become constant As the...

Explain how both temperature and concentration affects the rate of reaction in terms of collision model by DRAWING the reactants' particles behavior and motion at low and high temperature and likewise at low and high concentration in the boxes below (4 marks) Temperature effect: -High Low Concentration effect: High Low 3. Explain how both temperature and concentration affects the rate of reaction in terms of collision model by DRAWING the reactants' particles behavior and motion at low and high...
ch 14 answer each of these. answer all 3 please 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...
dy For a particular chemical reaction the rate (ghr) at which one of the reactants changes is proportional to the amount of that reactant present If y represents the amount of that reactant at -0.4y. If there were 50 grams of the reactant dt when the process started (t-O), how many grams will remain after 5 hours? The amount remaining after 5 hours is9 (Round to the nearest tenth. dy For a particular chemical reaction the rate (ghr) at which...
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...
3. Explain why, in a chemical reaction, the concentration of a reactant decreases more rapidly at a lower time t than at a higher t.
