Question 1: In the equilibrium expression for CaCO₃ (s) ⇌ CaO (s) + CO₂ (g), which components are included?
All three components: [CaCO₃][CaO][CO₂]
Only [CO₂]
Only [CaCO₃] and [CaO]
[CaO][CO₂]
Question 2: What happens to the reaction rate when the concentration of reactant molecules is increased?
The rate remains constant
The rate decreases
The rate increases
The rate becomes zero
Question 3: How many times greater is the hydrogen ion concentration in a solution with pH 2 compared to pH 6?
3 times
4 times
10,000 times
100 times
Question 4: What is chemical kinetics?
The study of chemical equilibrium
The study of reaction rates and mechanisms
The study of acid-base reactions
The study of chemical bonds
Question 5: When is chemical equilibrium attained?
When all reactants are consumed
When forward and reverse reaction rates are equal
When the reaction stops completely
When all products are formed
Question 6: What is a heterogeneous catalyst?
A catalyst in the same phase as reactants
A catalyst in a different phase from reactants
A catalyst that speeds up reverse reactions
A catalyst that only works at high temperatures
Question 7: For a strong acid like HCl, what happens during ionization?
Partial ionization occurs
Complete ionization occurs
No ionization occurs
Ionization depends on temperature
Question 8: How does temperature affect reaction rate?
It has no effect
Increasing temperature decreases rate
Increasing temperature increases rate
Temperature only affects equilibrium
