Question

How does the rate of reaction change with concentration?

Answer 1

concentration or pressure of reactants in a solution directly proportional to the reaction rate since additional responding particles are available in a similar volume

Complete step by step answer:
As the concentration of reactants increases, the pace of the reaction will increment. This is because of the increased numbers of reactant particles having more frequent collisions with one another. A more prominent recurrence of effective collisions will increment the rate of a reaction.
Rate constant is the constant of proportionality in the rate law condition and is equivalent to the rate of reaction when the molar concentration of every one of the reactions is unity. The rate constant is constant for a specific reaction at a specific temperature and doesn't depend upon the concentrations of the reactants. The unit of rate constant is directly proportional to the order of reaction.

Note: 1)At the point when the concentrations of the reactants are raised, the reaction continues all the more rapidly. This is because of an increment in the quantity of particles that have the base required energy. For gases, expanding pressure has a similar effect as increasing concentration.
2)At the point when solids and liquids react, expanding the surface area of the solid will build the reaction rate. A decrease in molecule size causes an increment in the solid's absolute surface area.
3)Raising the reaction temperature by $10{\text{ }}^\circ C$ can double or triple increase the reaction rate. This is because of an expansion in the number of particles that have the base energy required. The reaction rate decreases with a decrease in temperature.
4)Catalysts can lower the activation energy and increment the reaction rate without being devoured in the reaction.
5)Differences in the inherent structure of structures can prompt contrasts in reaction rates. Molecules joined by stronger bonds will have lower reaction rates than will particles joined by more weaker bond, because of the expanded measure of energy needed to break the stronger bonds
