What is a reaction rate?A.The speed at which a reaction occursB.The frequency of reactant collisionsC.The amount of products produced in a reactionD.The energy required for a reaction to happen

Describe what a reaction rate is and how it can be measured.

What does the reaction rate say about a reaction?A.It tells what the concentration of reactants is.B.It tells if a catalyst was used in the reaction.C.It tells how quickly products will be made.D.It tells what activation energy the reaction has.

How are the rates of chemical reactions related to collisions between reacting particles?Multiple select question.Reacting substances must collide at slow enough speeds for energy transfer to occur.Reacting substances must collide in the correct orientation.Reacting substances (atoms, ions, or molecules) must collide.Reacting substances must collide with sufficient energy to form an activated complex.

What determines the rate of a reaction?Question 2Select one:a.how quickly the mass of the system changesb.how quickly the scientist can stir the reactionc.how quickly the reaction gets hot or coldd.how quickly the reactants disappear and the products appear

How are the concentration of the reactants and reaction rate related?A.The concentration of reactants is a result of the reaction rate.B.Increasing concentration increases all reaction rates the same.C.Increasing concentration decreases all reaction rates the same.D.A change in concentration results in a change in the rate of a reaction.
