- Question 01:
A reaction that is considered to be fast, is likely to have which of the following characteristics?
- Question 02:
Which of the following changes in conditions will definitely result in an increase in the rate of a reaction?
- Question 03:
Increasing the temperature of a reaction increases the rate. Why?
- Question 04
In a reaction involving gases, which list contains factors that ALL contribute to the rate?
- Question 05:
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?
- Question 06:
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?
Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
- Question 07:
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?
- Question 08:
When solid zinc metal reacts with an aqueous solution of hydrochloric acid, which factors are relevant in determining the rate of the reaction?
- Question 09:
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?
- Question 10:
Changing the pressure of a reaction that takes place in the gaseous phase has which effects?
