Chemistry: The Rate and Extent of Chemical Change Flashcards
what must particles do in order to react
Particles must collide with enough energy in order to react
what four factors affect the rate of reaction
temperature, surface area, concentration of solution/pressure of gas, presence of a catalyst
what is the rate of reaction formula
rate of reaction = amount of reactant used or product formed / time
what 3 other ways can indicate a reaction has occured
colour change, change in mass, volume of gas given off
what is a reversible reaction
reaction where the product can be reversed back into the reactants
what is equilibrium
the rate of reaction either way happens at an equal rate
what does the position of equilibrium show
whether the concentration of products or reactants is higher
what is le chatelier principle
idea that if you change the conditions of a reversible reaction at equilibrium, the system will try to counteract that change
