In general, what is the relationship between reaction rate and reactant concentration?
Draw an energy diagram graph for an endothermic reaction where no catalyst is present. Then draw an energy diagram graph for the same reaction when a catalyst is present. Indicate the similarities and differences between the two diagrams.
How would you express the rate of the chemical reaction AB based on the concentration of Reactant A? Howwould that rate compare with the reaction rate based onthe Product B?
What is the effect on the rate constant and reaction rate when reaction temperature is increased? The rate constant will be greater, and the reaction rate will be higher. The rate constant will be smaller, but the reaction rate will be higher. The rate constant will be smaller, and the reaction rate will be lower.
Is CaCl2 (aq) + Na₂CO₃ (aq) → CaCO3 (s) + 2NaCl (aq) reversible or irreversible reaction
When the concentration of reactant molecules is increased, the rate of reaction increases. The best explanation is: As the reactant concentration increases, the rate constant increases. the activation energy increases. the frequency of molecular collisions increases. the order of reaction increases. the average kinetic energy of molecules increases.
How does increasing temperature affect the rate of reaction? the activation energy increases so the reaction rate decreases the reactants have more kinetic energy so the frequency of the effective collisions increases the reactants have more kinetic energy so the frequency of the effective collisions decreases the activation energy increases so the reaction rate increases
Which of the following changes leads to a decrease in reaction rate? A. Increase the reactant concentration. B. Increase the frequency of collisions. C. Lower the product concentration. D. Increase reaction temperature. E. Increase the surface area for a reaction. F. Lower the frequency of collisions.
Why does the rate of the reaction slow down with time? The rate constant slows with time because the reaction is exothermic and loses energy The reactants that react first are moving faster than the reactants that react last, which results in a slower reaction as time progresses The reaction rate depends upon the concentrations of the reactants. As the reaction progresses, the reactants are converted into products and their concentrations decrease The reaction does not slow down with time. The rate constant gets smaller with time so that it appears that the reaction is slowing The longer the reaction takes, the older the reactants become. Old reactants react more slowly than new ones so the reaction slows down
Which one of the following factors DOES NOT affect the rate of a chemical reaction? concentration C. temperature humidity D. nature of the reactants .The rate of a chemical reaction normally _______________________. increases as temperature decreases decreases when a catalyst is added increases as reactant concentration increases decreases as reactant concentration increases
How would the reaction rate change if you heat a reaction up? The reaction rate will increase Not enough information to tell. The reaction rate will decrease The reaction rate will remain constant
State whether the following changes will result in an increase in the reaction rate, a decrease in the reaction rate, or whether the reaction rate will be unaffected. •decreasing the surface area of a reactant •decreasing the concentration of a product •increasing the temperature •adding a catalyst
