The frequency of collisions is changed.
The concentration of reactants is changed.
A stress could be adding/taking away reactant/product. Or a change in temp and pressure (for gases). It depends on the system. Some of them get ulcers, but others just start drinking heavily. A system at equilbrium responds to a stress by shifting left or right (toward the reactants or toward the products) so as to minimize the effect of the disturbance. This is called LeChatelier's Principle. Some stresses can be a temperature change, a change in the concentration of one of the reactants or products, and a pressure change (if the reaction involves any reactants or products in the gaseous phase).
The more concentrated the solution of reactants, the more the reaction wants to push right making more products.Same goes vice-versa; if there's more products, then the reaction will push left producing more reactants.
The factors that change the reaction rates of chemical reactions are: 1)temperature 2)concentration 3)pressure 4)physical state 5)a catalyst
Temperature, atmospheric pressure (normal circumstances would be 1atm), percentage uncertainty of the equipment, loss of heat to your surroundings, parallax when reading scales such as a thermometer. And basically any variables that can be changed to be more accurate e.g your using cm's instead of mm's. Hope that helps :)
The frequency of collisions is changed.
The concentration of reactants is changed.
Examples: concentration of reactants, temperature, pressure, stirring etc.
There are several factors that affect the rate of reaction: -The surface area available. -Temperature -Availability of catalyst. -Concentration, if a/the reactant(s) is/are solutions. -Pressure, if a/the reactants(s) is/are gases. -Reactivity of reactants. -Activation energy of the reaction.
Sometimes the changes in state will affect how the reaction works or even if it will work at all.
