A reaction that is considered to be fast, is likely to have which of the following characteristics?
Which of the following changes in conditions will definitely result in an increase in the rate of a reaction?
Increasing the temperature of a reaction increases the rate. Why?
In a reaction involving gases, which list contains factors that ALL contribute to the rate?
In a reaction that involves solid magnesium carbonate, it is observed that when the carbonate is ground into a fine powder, that the reaction occurs at an increased rate. What is the best explanation for this observation?
In the reaction between zinc and hydrochloric acid (below) it is found that the rate of production of hydrogen over time, decreases. What is the best explanation for this observation?
(s) + 2HCl (aq) → ZnCl 2(aq) + H 2(g)
Decreasing the volume of a vessel that houses a gaseous chemical reaction
that ultimately goes to completion, will have which of the following effects, and for what reason?
When solid zinc metal reacts with an aqueous solution of hydrochloric acid, which factors are relevant in determining the rate of the reaction?
When the temperature of a reaction mixture of gases is increased, the Maxwell-Boltzmann distribution of energies is observed to shift. What can be said of the total area underneath the distribution curve for the higher temperature, when compared to the lower temperature?
Changing the pressure of a reaction that takes place in the gaseous phase has which effects?
