29 (6 pts) How do concentration of reactants, temperature and catalysts affect the rate of a chemical reaction? Explain. Concentration of reactants: mcreases more collisions within the reactants. collisions Temperature: Increase in temperature causes increase in more and more energy in collisions. (increases rate? Catalyst: Lowens energy of activation of reactants cate? (increases rutes

Effect of a Catalyst on Reaction Rate: with a lower Ea than for the uncatalyzed reaction. This is shown as the blue path with Ea in the diagram below t a given temperature, a catalyst increases the rate of a reaction by providing a pathway E (RJ) products Reaction Coordinale Since the potential energy barrier is lower in the presence of a catalyst, a greater fraction of the molecules will have sufficient energy to react. Because the reactants and products...

Which of the following provide(s) a valid description relating collisions and reaction rate? Decreasing the reactant concentration will increase reaction rate because if there are fewer particles there is more room to collide. Increasing the temperature will decrease reaction rate because if the particles are moving faster there will be fewer collisions. both of the above neither of the above

Question 13.42 update
to study the effect of reactant concentration on reaction rate is to initial rate depends on the starting concentrations. It is preferable rates because as the reaction proceeds, the concentrations of the and it may become difficult to measure the changes accurately, be a reverse reaction of the type products rightarrow reactants which would introduce error into the rate measurement. Both of these virtually absent during the early stages of the reaction. Table 13.2 shows three rate...

Explain why each change in conditions would affect the reaction rate of reaction when sodium metal reacts with chlorine gas to form NaCl? As a catalyst is added to the mixture the reaction rate will increase because As temperature decreases the reaction rate will decrease because As volume decreases the reaction rate will increase because As concentration increases the reaction rate will increase because As the surface area of a molecule is decreased the reaction rate will decrease because As...
